Comet Crazies and two nights

Friday night, The Astronomy Connection (TAC) held a star party at a middle school in Los Gatos, California, for the public to come out and get aquainted with Comet Hale-Bopp. As sunset approached, the number of telescopes we had exceeded 20, brought in by active observers from Monterey, the upper San Francisco peninsula, and out into the East Bay. This is a large geographic area, and can testify to the desire and willingness of like-minded observers to travel unusual distances to share views and camaraderie. Before the sun fell behind the Santa Cruz mountains, roughly a hundred interested members of the public had gathered, along with local newspaper photographers, looking at the hardware, which included an 18" Obsession, 18" Sky Design, 17" home-built, 14.5" home-built, several 10" and 8" dobs, a number of Meade LX-200's ranging in size from 12" down to 8's, a Celestron Ultima 2000, Astrophyics 130 and Traveler, Takahashi 128, Miyauchi 20x100 binoculars, and many other wonderful optics. The crowd loved it.

Soon, the comet blinked into view below a few wisps of cloud drifting slowly in the west, from north to south. The excitement in the crowd was electric, as all heads turned northwest and voices murmured "right there" and "just under *that* little cloud. Binoculars and telescopes quickly swung into action. The owner of the 12" LX-200, being new to large crowds at events pushed by the press, commented to me twice that there were "too many people!" And in fact, had we fewer than what at that point must have easily been 25 telescopes set up, the crush would have been unbearable. Lines were long at all the equipment, and more people could be seen streaming into the school yard from the parking lot.

All sorts of questions were asked. What are the "rings" around the front of the comet. What will happen to it? Have they ever hit the earth and what would happen? What are they made of? How large are they? Where do they come from? And, of course, the usual gasps of amazement and comments on the beauty of the view in binoculars, where the extent of the visible tail could be appreciated.

We received thanks from so many people, it was an extremely rewarding evening. Of course, when the comet dropped into the muck, scopes turned to the other celestial delights. M42, Mars showed wonderful detail in the 5" Takahashi and in a 17" dob (with off-axis masking), M41, M46, M81 and M82, M65 and M66 with (much to my surprise) the companion NGC3628, and many other objects.

Finally, about 11:30, the crowds had gone home, as had many of the scopes. Although there was some haziness that night, making the sky brighter than it might otherwise be from that location, all who were there agreed that for an in-town site, it was worth coming back to. We will hold another star party there on April 11, and I expect the comet fever will have reached maximum brilliance by then.


The next day many TAC participants drove to Fremont Peak ahead of the expected crowds. I picked up my observing friend and loaded his 20" Obsession into the back of the truck, making the 14.5" already in there look rather small. :-(

It was an unusually warm day in early spring, probably at or above 80 degrees, and not a cloud in the sky. Even the air quality was good, as the hills all around Silicon Valley were visible with surprising clarity. We drove down highway 101 (a.k.a. the "El Camino Real" or King's Highway) toward San Juan Bautista, through the usual bottleneck of gawkers viewing someone getting a traffic citation in the median, past the discount outlet malls, past the appetizing aroma of garlic that permeates Gilroy . Suddenly, looking up, we were amazed to see a cloud above.... OH NO.... above Fremont Peak. Could it be that the only cloud in northern California decided to park itself over our observing site? Or, was the park so packed already that what we are seeing is the smoke from hundreds of afternoon bar-b-ques? After winding our way (painfully slowly, when my buddies' 20" scope is in tow) 11 miles up San Juan Canyon Road, the road opened up into the top of Fremont Peak. Look... thin clouds. No campfires with weenies smoking up the sky. What was this? Around the bend to our setup area, we found several TAC members there already. They told us a controlled burn was taking place to our south toward Salinas, but things were improving rapidly.

So, we decided to stay. The park was relatively empty, except for some hikers, so things seemed to be okay.

Soon, much of the equipment that was at the in-town event the night before, began showing up. Double parking was a first time sight for us. As dark approached, tourists began appearing everywhere. It rapidly occurred to me that the park had become inundated with tourists. After dark set in, one could look down the hillside to the camping areas and literally see lines of cars, some with headlights on, others with them off, in a slow parade around the single lane roads of the park. We heard all parking places were occupied, and rangers were for the first time to my knowledge, directing traffic in the middle of nowhere on a mountaintop 2300 feet above the Monterey bay. What a zoo.

The comet was to blame, of course. I watched the comet until real dark set in, then the 14.5" and 20" began hunting Hershel objects.

This would be fun. For the first time I was entering the confines of Coma Berenices. The objects, unlike other dimmies I'd been viewing lately, were big and bright. And there were so many! Probably the most frustrating experience was looking for M88, because all we had was an NGC number to work with, and our chart (HB Astro-Atlas) only showed it as a Messier number. We kept checking the coordinates, saying "yes.... it should be right about THERE.... but "there" it wasn't". Finally we looked in the Uranometria Field Guide and sure enough, the phantom NGC was indeed M88. It was also fun to work a compact area of the sky. after such large constellations as Cetus, Draco, Ursa Major, Leo, etc. I became much more familiar with the stars in Bernice's Hair. Of the memorable sights, the old favorite NGC4565, with it's width, brightness, and super dark dust lane, certainly ranked high. Also fun was placing the eyepiece (19mm Panoptic) on M84 and walking galaxy by galaxy to and beyond M91, all in all, perhaps up to a dozen galaxies viewed by just drawing the field of view toward myself, with never a field without a galaxy in view. What a rich part of the universe we can see with a modest sized telescope!

But, the night had it's downsides too, at least for serious galaxy hunting. Each time I would abandon the eyepiece to check a chart or peek over toward the comet, I would turn around to find some stranger at my eyepiece, just an interested member of the public amazed to find "big" telescopes to look through. Of course, since we are all ambassadors of the hobby, courtesy stopped me from telling them to get the hell of the ladder and go away ;-) and instead I would usually put the object back in the field of view and explain what they were seeing. It is always fun... although it makes me think of the solitude and long nights we had during the past winter, observing without the comet, the tourists, the fires, the traffic jams and hordes of gawkers that made the past weekend unforgettable.

Soon this comet will pass, remembered fondly for its beauty and how it for a moment stimulated the public's imagination and interest in astronomy, and we will return to the normal craziness of summer time observing at Fremont Peak. Just a few more weekends until then.

I think the next dark sky TAC event will not be until the comet passes. Peace and quite are beginning to sound like a nice companion.

Comet / Summer's Approach

My wife wanted to see the comet, so I set the alarm clock for the absurd hour of 5 a.m. Having had cloud cover in the morning the prior day, I figured I'd get to sleep in and avoid an angry spouse and disappointed kids.

Well... 5 a.m. came and the clock-radio announced wake-up time. I quickly (and unstabily) went to our north facing bedroom window. Ah! Cloudy! NO... no... a star. No, not a star.... er.... huh? Hale-Bopp? Geeshhhh loooooookaddat!!! Hey.... honey..... get up!

I had placed the small scope (8" f/7 dob) out back with three eyepieces the night before. :-) This will be good... On went the coffee and out the back door I went. Hey... I can see it from the other side of the pool...

So, there I set up, with a kitchen chair putting me right at the eyepiece. My wife (Pat) came out and was floored at the visual appearance. Tail standing on end.... several degrees naked eye, pointing almost toward Vega. Out came two kids... standing there in the breaking dawn, all enjoying the view together.

Hey.... look.... the summer triangle is out, and immediately those warm night relaxing around the pool, up at the Peak, Lassen, friends, summer vacation.... all seemed to be around the corner.

But, back to the comet... 35mm eyepiece... nice wide view. The jet and waves (yes... Mr. Adler, it does look helical) shown nicely. In goes the 20 wide-field. Wow. Structure... in the dob it was a left handed comet... as one was taken in by the jet exploding off one side... it was easy to overlook the delicate material off the less active side of the nucleus. In went the 10.5mm and a stunning view... material coming off the nucleus almost directly toward the sun. The material from the jet looked to me like the crazy pattern described by a missle trail in the evening twilight... twisting and turning... luminous against the darker sky.

It is certainly worth getting up for.

Finished off the viewing as the sun washed out the dark... by looking at Alberio. Gold 'n blue jewels. I've forgotten what a fun scope the f/7 is. I think I'll put a Telrad on it and give it to my kids.

I know there are plenty of people shooting this ice-ball with cameras...

BUT.... I can't wait to see Gleason's shots through the 7/7! John... tell me how much your best print will be.... I'm putting my order in now!

Photon Feast with dessert!

Yesterday, the San Francisco bay area had a one day break from the cloudy/rainy winter we have been having. It was a thoroughly inexplicable occurance, since this was a nearly moonless Saturday. So, after the usual morning family obligations, I began fielding phone calls from astro-friends wondering who was going to Fremont Peak. Everyone had a bad case of photon-deprivation were ready to rumble on down....

Leaving the south bay, the drive is short... 37/10000ths of a light second and you're at the Peak. You're there in a flash. What a great trade... that quick drive to see objects 50 million light years away... plus some spectacular "object du jour" that were unique and unexpected...

Arriving at "The Peak" at 3:30pm, I found the observing area nearly full. Huh? Is this mid-summer or early February? What's the deal with the crowd? Ah... yes.... the lure of clear skies... enough to make any California astronomer brave the near freezing night temperatures!

I set up the 14.5" dob and began admiring the variety of equipment. Want to check out a wide array of astronomy gear? The Peak is da'place. 20" homebuilt dob, 18" Obsession, 18" Sky Design, 17" homebuilt dob, 12.5" Orion dob, 8" Meade SCT, 8" Meade LX 200, 12" Meade LX 200, 18" JMI NGT, 6" Cave Newtonian, 7" Questar (loaded), 4" Takahashi, 6" Astrophysics, 5" Astrophysics, Astrophysics Traveller... many, many others... and ... oh... the 30" Challenger reflector in the Fremont Peak Observatory.

As twilight was becoming night, we started looking for some satellites one member of our group had sent us as an observing schedule. Satellites? Well, what the heck... maybe its cool... I did enjoy seeing the Shuttle re-enter last summer. I got my 10 x 50 binos ready...

First was... the "Disco Ball".... heh heh heh... I can't believe I was looking for something named after one of (IMO) the wierdest fads in American dance. OK... just above Polaris... 6:44pm... HEY....WHAT'S THAT? Unreal! That buggers blinking erratically, quickly, brightly... it's the Spastic Saturday Night Fever Sat! Kewl... ;-) It was quite a sight. A half dozen of us or more watched that 7' mirror covered sphere tumble across the darkening sky.

Soon after, a few degrees above Deneb, the bright visage of Mir crossed. Man, that baby moves. I tried to see a supply ship nearby, but was unsuccessful.

I have to admit that awhile later I was probably the only person at Fremont Peak who was unable to find NOSS cross the northern sky. NOSS is three satellites flying in formation very close to each other. I had seen it a year ago... and believe me, seeing such a strange sight might lead one to consider the possibility of alien visitation.

Now it was dark enough to observe. The Hershel Hunt began. Forty *7&&))*@ minutes to try and find the first one in Eridanus. Arrrrrrrr.. blow it off... too low.... to bright on the western horizon. Up to... Gemini? Yes... nicely placed if you don't mind using a ladder. First to ngc2371/2372, a bi-lobed planetary just south of Castor and Pollux. Hmmm... seen it before. OK... on to some galaxies... ngc's 2274 2389 2435 2481 and 2275. These were all easy targets, with good bright stars to hop from. These galaxies ranged from (approx) mag 13.5 to 14.5, and all were small objects.

Soon, Gemini was near zenith, making it difficult to operate the dob, so we began woking Leo. I had been in Leo the past two years, looking for Herschel objects, and my observing partner questioned whether we were nearing the end of the constellation. Ha! Leo is sooooo rich, I showed my friend three unmarked pages of objects still to be located.

Most of these objects seemed to be in the areas between the upper-back-side of the curve of the "question mark" and Leo Minor, and between Regulus and the Hydra/Cancer border. Ngc's 3900 2872 2906 2968 2970 3020 3067 3070 3274 3300 3437 3016 2874 and 3024. Some of these were *very* small... on the order of .5" x .7" of arc, and 13th magnitude and dimmer. Several challenging objects were west of the back triangle of stars in Leo, toward Leo Minor, where there are few good stars to hop from.

About now, one member of our crew came by and asked about a supernova in a distant galaxy located in Virgo. We looked through my 14.5" and felt we could see a bright point of light in the galaxy, winking in and out. Over to the 12" LX-200 to comfirm the location... yes... right one... and the blinker was there in that scope too. Over to the 18" Obsession, confirmed! Imagine... seeing the light emitted from a single star at such distance! Good stuff.

Now, it was getting cold. There was ice forming on the tops of several cars. I had enough layers on to make movement noticeably affected. But, any moisture in the atmosphere had frozen out, and the sky was very clear. It was about 2:30am and I moved up toward Ursa Major. This is another incredibly rich area for galaxy hunters. As I began, I thought of the Hubble Deep Field photo, and was, as always, humbled by the size and depth of the cosmos. But, I pressed on despite my insignificance. :-) Since I had done so little work in Ursa M, I had lots of nice bright stuff to look at! All mag 11 - 11.5, what a treat. I hit ngc's 3992 2681 2976 2975 and 3077. My partner had sat down in his chair as I swung up toward this section of sky. His replies to any discussion had been reduced to Cro-Mag grunts and at times, simple non-responsiveness. Soon, he was having uncontrollable yawning attacks and I knew he had to go before we all were afflicted. So, off went my friend, with about four or five other vehicles. I suddenly felt alone.... as I was the only scope set up on that part of road.

I walked over to the other big dobs and two LX-200's. Everyone was sitting, relaxing, talking, drinking coffee and hot chocolate, looking forward with anticipation to comet Hale-Bopp. From memory I began naming summer ngc and Messier numbers to try on the 12" LX-200. We kicked around in "summer" for a while, and thought about shirtsleeves and shorts (and mosquitos), about cold drinks on warm nights, short-all-niters, trips to darker skies, and more.

Now fatigue was beginning to take over. I walked aimlessly around for a while... looking to the east for the bright traveller to appear. I had not seen the comet since last fall when it was in Scutum. Would it really be *that* much bigger and brighter?

Suddenly, a disembodied voice in the dark called me to some 16 x 70 tripod mounted binoculars. ____OH____MY____GOD

What a coma. Was that a plume off the side of the nucleus? It must be. Look how big and bright it is. Is it another Hyakutake? No way. No, it is different, magnificent in its own right. This comet was not the "beauty queen" we saw a year ago March, this comet was, instead, specatular for its sheer size and activity. I had to see it through a telescope!

I walked over to the 6" AstroPhysics. Well, the nucleus had an active geyser spouting 90 degrees away from the tail. In the fountain was, well, clouds. And, material was not just coming off in the plume, but all around the nucleus. the coma itself was quite a sight... think of how the Ring Nebula is illuminated brightly at the edges of the "bubble" but not in the center. That is how HB's coma appeared to me. Like a distended upside down "U" with the area behind the nucleus being (to me) clear in appearance. The coma was bright along the edges, and the side with the brilliant fountain had a brighter coma.

And to think this is going to become brighter and larger....

I went up to the observatory and had a look through the 30". The fountain had the appearance of clouds as it seemed to have come off the nucleus in waves or bands. This one will be a DON'T MISS IT show in a month.

About then I began noticing the all nighters fatigue showing among others. One fellow, trying to look through a dob at the comet, rocked back a bit too far and rolled onto his rear-end and back (no harm). Someone pouring hot chocolate seemed to miss their cup and spilled the hot liquid all over the roof of their car (quickly melting the ice).

I had enough observing. The dawn was quickly approaching. It was after 5am. I crawled into the back of my truck, dressed like an Eskimo on Mars, and quickly was asleep.

I awoke at 8:30 to the sun ringed by a multicolored halo from high thin clouds extending in a V shape from Sol to the north-western horizon. We had tasted every last morsel of this flukey break in California's winter weather pattern. It was delicious, and I certainly had my fill.

As I stumbled out of my truck, all that was left were a few other all niters asleep in their vehicles, and a good size hot chocolate pond in the parking lot.

I drove relaxedly down the hill, past the horses with their winter coats, past the cows having breakfast, past the sheep and past the rushing stream following San Juan Canyon Road... back toward "civilization" a mere 37/10000ths of a light second away...
