New Comet for the New Year

spac3manspiff writes "The news has several stories about a fairly new comet named Comet Machholz discovered by Don Machholz. The comet will be able to be seen in the sky on Jan. 1 and Jan. 2 or Jan. 5 through 8. Along with the comet's appearance: Mercury, Venus, Mars, Jupiter and Saturn will all be able to be seen with a naked eye this month. However, you will need binoculars to see the comet."

      Besides I wasn't gonna stand out there in my bvd's for very long, I've got a cold & miserable.

      But, if it was clear, I'd sure have my 7x35's out to take a look, it seems that the huge majority of the so-called naked eye comets have coincided with mostly overcast skys for the last 20 years.

      Its a crying shame when man can't see off the planet he was born on, and its man thats responsible for most of the dirt in the air. But I can remember when you could see forever almost everynight, back in the late 30's thru the early 50's. The milky way was blazingly bright against a black velvet sky covered with twinkling stars from horizon to horizon.

      And then man moved to town and took up selling the real estate where the skys were truely clear, to some developer, putting up street lights and other crap to blind us all...

      But don't blame me, I wasn't that man. I was busy learning how to fix this newfangled thing called TV back then.

      Unfortunately, it won't. Hyakutake made a fairly close pass at earth, and hence put on a pretty good show. Macholz will be over 1/2 an AU away at it's closest, and from the data I've seen so far, it looks like it's a fairly small comet. There's just not enough surface area to allow the kind of sublimation needed for the comet to become bright (although that does not rule out some kind of outburst occuring). Also, this comet is nearly at opposition when it will be at it's brightest, meaning that the earth is almost directly between the comet and the sun, so the tail is pointing almost directly away from earth, which means you won't see a nice long tail either (even if by some chance the comet flares up and becomes real bright for a few days).

      Personally, when I'm hunting for this comet, I always start at Orion, it being one of the easiest constellations to recognize (just look for a straight line of 3 bright stars).
      - Above and to your right of Orion (when he's standing straight up) is Taurus, of which bright orange Aldebaran is most visible.
      - Keep following that line a few more degrees (I'd say about 3 fingers, your arm stretched out) and you'lle see a fuzzy 7-star cluster - that's the Peliades. Ninth of this month, the comet should be right next to it.

      I just happened to be out looking at this comet and what do you know, /. has an article about it when I came back inside.

      I found it pretty quickly from the guide in Sky and Telescope, although the suggested spotting map will work just fine, too. I used a pair of 10x30 binocs and spotted it almost instantly. Took me another minute to make sure I wasn't looking at some other nebula. My non-techie wife was able to spot it just about as quickly - said it kind of pops out at you as you scan the heavens in the general area.

      It's just a "dim fuzzy", and probably won't get much brighter, but it's cool to see. Set up my 6" telescope to see if the view was better. Kind of, but no further definition to speak of. Still definitely worth hauling out the binocs.

    It is these types of comets that frustrate people who are interested in astronomy but don't know where to look.

    You will not see it with the naked eye unless you are under very dark skies away from city lights. You will have more luck with binoculars and even then it will only appear as a dim smudge of light.

    Finding it in the sky will be an exercise in frustration unless you are already comfortable orienteering the night sky. Your best bet will be on January 8th, when the comet will be just to the right of the Pleiades, an easily locatable star cluster in Taurus.

    This page at Sky & Telescope has a decent finder map. Happy hunting and even if you don't see it, enjoy the night air. It's good for you...

In fact, it's moving away from the comet each day and approaching being a new moon, so viewing based on the moon will be better on the 3rd and 4th than on the 1st and 2nd. And, from the Sky and Telescope atrticle: "Around the 16th, moonlight again begins to seriously intrude.", which marks the first impact this year that the moon will have on the viewing.

  10. Thoughts for observing by jesterzog · · Score: 4, Informative

    The news has several stories about a fairly new comet named Comet Machholz discovered by Don Machholz.

    It's been quite bright (for a comet) in southern hemisphere skies for about a month now, and it's certainly worth going out to look at. I went out to look at it (from where I live in New Zealand) on December 11th. It was very easy to find in binoculars then (although I'm an amateur astronomer)... that was about mag 5.5. I haven't had a chance to see it since then because of bad weather.

    If it's approaching mag 3.5 as the article suggests, it's getting very bright for a comet. If you're in reasonably unpolluted skies and know where to look, you might see it with an unaided eye. If you can't, though, you could probably see it in binoculars at least from low-lit suburban areas if you keep away from glare. Look with binoculars anyway, if you can, and you'll see a lot more. Frequently a reasonable pair of binoculars will reveal a lot more than a toy department store telescope.

    If you're not sure where to look, keep in mind that you may also be able to contact a local observatory or astronomical society, and ask if they're having any open nights where you can have a look at it.

    Don't expect anything really spectacular, of course. Most comets are a smudge on the background of the sky. Give your eyes time to adjust to what you're seeing, too. Like most thinks in amateur astronomy, you see more for the longer that you look at them. If you watch the comet over several nights, you may also see the appearence change quite a lot.

    The linked yahoo article is quite misleading when it mentions brightness. It states that it's possible to see down to mag 6.5 in the most unpolluted skies. I think the author is confusing the difference between point sources of light, such as stars, and other sources. Comets are diffuse objects, and the comet magnitude describes the total amount of light that the surface emits. For this reason, a comet will appear significantly fainter than a star of the same magnitude. The exact difference depends on just how diffuse the comet is. Keep in mind, though, that even though it's bright, it's unlikely to leap out at you.

    The most striking thing about that cult was how they made their living.

Consider that Manson et al were forced to live in low rent districts of southern CA like Death Valley, and got all their food from dumpster diving at supermarkets. If you're in a cult and needing a source of cash but not wanting to call attention to yourself, computer work is great. Everyone expects you to be weird. Sure, Nikes, bald head, whatever.

    It was very strategic for them to commit mass suicide like that. They bailed out of the web-design market at the right time.
