This coming week is perhaps the best time to look for a new comet in
our evening skies, as long as your expectations are not set too high by some of
the media attention it has received.
The comet – a chunk of ice and dirt from the distant backwaters of the
solar system – is falling around the Sun with closest approach to our star on
Sunday, March 10th.
For the next week, it will be visible very low on the horizon if you
look toward the west. Tuesday and
Wednesday it will be near the crescent Moon and may be easier to spot as a
result. But here are the problems beginners
will need to keep in mind:
1. It’s so low in the sky you will need to look for it from a location
where you have a clear view all the way down to the western horizon -- and no
hills, buildings, or trees in the way.
Out by the ocean is really great.
2. Things on the western horizon are SETTING – going quickly below the
edge of the sky. That means there is a
very short window to see the comet. Try
too early, and the sky is too bright with sunlight. Try too late, and the comet is below the
horizon. About 30 - 45 minutes after
sunset is what experts are recommending.
3. If there are clouds or fog in the western direction, or you’ve got
bright street or car lights in your view, the comet may be too hard to
see. In March, weather is an issue in
many locations.
4. And the comet is so far from Earth, it is not spectacularly bright. In
general, binoculars may be needed to pick the head of the comet and the faint
upward-pointing tail out of the glow of the sunset.

By the way, if you are wondering about the strange name for a comet, it’s
taken from the automated survey telescope in Hawaii that discovered it in 2011:
the Panoramic Survey Telescope and Rapid Response System.
