    COMET HARTLEY 2 UPDATE: Comet 103P/Hartley 2 continues to approach Earth for an 11-million-mile close encounter on Oct. 20th. It is not yet visible to the unaided eye, but amateur astronomers are finding it easily using backyard telescopes. The comet's vivid green atmosphere now subtends an angle equal to some of the biggest craters and seas on the Moon. Visit http://spaceweather.com for sky maps and latest images.

    I just read about this for the first time yesterday. I forgot to take the binocs out. I'll certainly try it tonight.
    No weather forecasts are ever guaranteed, even if confidence level is high. Even a 99% probability will miss 1% of the time. That's the best anybody can do when predicting highly complex events.

      I think I saw it last night with the naked eye. I live a rural area and it is almost as drak as it can get. Last night when I was walking the dog I notice a green glow almost straight up. I was thinking that it was strange. Now I see this about a comet. I will look again tonight with the binoculars.

        I can't see it. I'm using binoculars looking exactly where it's supposed to be, and all I see are faint stars. I'm in the Indy suburbs, but looking away from the city. If it's 5-7 mag., I should pick it up with no problem.

          You need a telescope.

            Where in the night sky is the comet? I was thinking of breaking out the telescope tonight.

              Dates are UTC. So the "9" marker is where the comet was on the evening of the 8th in the USA. The comet is just a little to the left of the "9" as I write this.

              EDIT: I embedded the JPEG, but it's way too big.
