http://vimeo.com/61596987NASA scientist Fred Espenak captured this wonderful timelapse video of Comet PANSTARRS as it set over the Dos Cabezas Mountains in Arizona. The photos were taken from San Simon, AZ using a Nikon D90 and Nikkor 18-200 VR zoom lens at 200mm. All exposures were 2 seconds at F/5.6 (ISO 800).

(36,302 posts)The past three days were all hazy to overcast -- finally caught a glimpse of the comet tonight, just minutes before it set. High cirrus clouds kept sweeping in front of it up to that point.

(57,656 posts)I had gone out Tuesday night to look, but I didn't see it. After seeing your post, I tried again last night (Thursday). I found it. I'm in northern Virginia, 38.8 degrees north latitude. I could almost make the comet out with the naked eye, but not quite. With binoculars though, there was no doubt. Local sunset on Thursday was 7: 14 or so. I was able to see it from 7:30 on. I do not have an unobstructed view in any direction, so once the comet was in the trees, it was gone. But for them, I would have been able to follow it longer. The tail is much more vertical in appearance now.

(27,677 posts)Explanation: Have you seen the comet? As Comet PANSTARRS fades, careful observers -- even with unaided eyes -- should still be able to find the shedding ice ball on the western horizon just after sunset. Pictured above, Comet PANSTARRS (C/2011 L4) was pointed out from a hilltop last week on First Encounter Beach in Massachusetts, USA. The comet was discovered by -- and is named for -- the Pan-STARRS astronomical sky survey that discovered it. As the comet now recedes from both the Earth and the Sun, it will remain visible further into the night, although binoculars or a small telescope will soon to be needed to find it.
