Cometary crowd-pleasers

Comet Holmes gives off a fuzzy glow in a FirstPerson snapshot taken Nov. 12.


You could say that Comet Holmes is the "people's comet" because it's been so widely seen and photographed by regular folks over the past few weeks. Now that the comet is beginning to fade, it's a good time to check out some of the greatest hits, including a FirstPerson time-lapse view.

The view above is a FirstPerson contribution from John Stephenson of Wappinger Falls, N.Y. This picture of Comet Holmes was taken just before 10 p.m. on Nov. 12, with a Nikon digital camera attached to an 8-inch Schmidt-Cassegrain telescope.

The time-lapse view, seen at right, shows how Holmes' fuzzy dust cloud grew over the course of several days from Oct. 28 to Nov. 2. John Goode contributed this composite from Bandera, Texas.

As we discussed last week, the comet made a splash back on Oct. 23, when scientists believe a piece of the nucleus broke off and disintegrated. Over the weeks that followed, the cloud of debris spread out, giving the comet a ghostly appearance in the night sky.

SpaceWeather.com reports that the comet's brightness is fading as it recedes from the solar system's center - and it's now said to be nearing the edge of naked-eye visibility. Tonight provides a good capper to the sky show, as the comet passes right in front of Mirfak, the brightest star in the constellation Perseus. This map helps you locate the fuzzball in relation to the easily recognizable "W" of Cassiopeia's chair in northern skies.

Aye is sure is a good spectacle! :)
In no way is Holmes "nearing the edge of naked-eye visibility" as the light curve shows: It's just getting fuzzier every day, and so you need darker skies (and the Moon out of the way) to see it well. Plus - after leaving the vicinity of glaring Mirfak - Holmes is now moving into a region of the sky pretty devoid of bright stars, so it should actually be more obvious in late November than now.
