Tips offered for best look at comet visible this week

Last week you heard about Comet PanSTARRS, also known as C/2011 L4.
The Bays Mountain Astronomy Club called The Erwin Record last week and ask us to let readers know they will have five special viewings for the comet this month. There is already the StarWatch viewing sessions each Saturday night in March and April.
But, with the addition of two more sessions on March 13 and 20, there will be a total of five viewings dedicated to the comet. The viewings are free and all are welcome.
The key observing sessions and start times offered for the comet are: March 9 at 6:30 p.m., and then March 13, 16, 20 and 23 at 7:30 p.m.
If the weather is fully cloudy or raining on the CometWatch dates (13 & 20), then that session is cancelled.
You can call Bays mountain at 229-9447 or visit for more information.
Since the peak viewing time is projected to be the nights of March 12 and 13, I wanted to share this article from NBC with tips on how to get the most out of comet PanSTARRS.
Now that it’s become visible in the Northern Hemisphere — but if you’re not properly prepared, the experience can be underwhelming. You have to know where and when to look, and with what. Fortunately, there are lots of resources to draw upon.
First, some quick facts: Comet PanSTARRS is thought to come from the Oort Cloud on the solar system’s edge, and is making its first round through the inner solar system. It was discovered in 2011 by the Pan-STARRS Telescope team, but it didn’t attract wide attention until last year, when astronomers noticed a brightening trend that promised to produce a sight visible to the naked eye. The comet is expected to shine brighter than the stars of the Big Dipper over the weekend.
The challenge is that during this time of peak brightness, the comet will be visible quite low near the western horizon, just after sunset. “Look too early and the sky will be too bright,” NASA postdoctoral fellow Rachel Stevenson said in a PanSTARRS preview provided by the Jet Propulsion Laboratory. “Look too late, the comet will be too low and obstructed by the horizon. This comet has a relatively small window.”
The farther north you are, the closer to the horizon you’ll have to look. Those aren’t exactly ideal conditions, especially if you have an obstructed view to the west, or if there are clouds on the horizon, or if there’s significant haze in the air. The best viewing spots should be at higher elevations, far from haze and the glare of city lights, where the skies can get as dark as possible as soon as possible after sunset.
Depending on your location in the Northern Hemisphere, you may not be able to get a good look at the comet until next week. But even if you miss seeing it on Thursday or Friday, it’s worth checking out a variety of spots over the next few days to get ready for the peak experience on March 12 and 13. That’s when Comet PanSTARRS is due to make a pretty appearance close to the crescent moon.
Although the comet has become visible to the naked eye, you’ll want to pull out the binoculars to make out the comet’s tail. You might notice two elements to the tail, pointing in slightly different directions: One element is made up of glowing ionized gas, while the other is made up of dust that reflects the light of the sun.
PanSTARRS is due to make its closest approach to the sun on Sunday, coming within 28 million miles (45 million kilometers). On each evening after that, the comet’s position will be slightly more elevated from the horizon, and shift slightly to the north. It’ll also become dimmer. By mid-April, the comet will no longer be visible to the naked eye, even under the best circumstances.
When PanSTARRS fades from the spotlight, don’t put your binoculars back in the attic: Another starry messenger from the outer solar system, known as Comet ISON, is due to make its appearance in November. Some skywatchers have dubbed ISON the “Comet of the Century” because the most optimistic projections suggest it could shine as brightly as the full moon. It’s way too early to make firm predictions, but it’s a good bet that the comet-watching skills you develop while looking for PanSTARRS will come in handy when it’s ISON’s turn.
