    i've seen it quite a number of times, tuesday night most recently

    once from inside my apartment, which is in a very large city, so there's plenty of light pollution

    i think it's phenomenal, but i tried explaining how unusual this sudden explosive outgassing is to a couple of friends and they were more astonished by the fact that it's inside our solar system than that it's 150 million miles away and yet still looks like a huge dandelion in the sky...

    Nice.

    It's too overcast tonight but I'll definitely look out for it tomorrow.

    Not sure, but I think it'll be visible at night where you're at, weather permitting of course.

    FYI here's a sky map that shows where it is --

    How to see Comet Holmes late October and November

    take the 2nd stroke of cassiopiea's "w" and follow it down from the w (the two stars point to comet holmes the same way that the "pointer" stars of the big dipper point to the north star)

    it's about halfway between cassiopeia and the pleiades (the "seven sisters")

    naked eye visible if you know where to look, and absolutely impossible to miss with binoculars

    I didn't pay particular attention to the details of WHEN it'll be visible (early evening, late at night, pre-dawn).

    I'm going to have a look tonight too. So presumably if this thing is the size of the sun, it should be quite big but much fainter (otherwise we would have no night). Is that right?

    Well remember the size that we see it depends on its distance from us... and it's really far away...

    It's not that much farther from Earth as the Sun is from here. IIRC it's only about 1.5 times the median average distance.

    Then it should be quite large when you see it?

    Not necessarily. The coma of a typical comet is not uniformly bright all over, especially once a tail starts to appear (as is the case with the Holmes comet). It gets dimmer as you go out from the nucleus to the edge of the coma, which will make it about twice as large as a typical red giant or supergiant star (like Betelgeuse or Sirius) at best, depending on where you are and how much light pollution there is.

    I'd love to see what it looks like through a telescope.
