Watch a bright comet head for the sun

Posted by Andru Edwards Categories: Cameras, Internet, Science,

Soon after Australian amateur astronomer Terry Lovejoy discovered a comet in an automated search program using a telescope equipped with a CCD detector on Nov. 27, it became clear that he had found something special.

Follow-up observations determined that the comet belonged to the Kreutz group of sungrazing comets, so called because members of this comet family—which all travel in similar orbits—pass extremely close to the Sun. The brightest Kreutz comets, such as the great comets of 1066, 1843, 1882, and 1965, have been among the most spectacular comets on record. The Kreutz group is believed to be the remnants of what was once a single, larger comet that has progressively fragmented over the past couple thousand years.

Although Lovejoy's comet—now officially known as C/2011 W3 (Lovejoy)—is not expected to rival the greatest Kreutz comets, it’s the first sungrazer to be found by a ground-based observer in over 40 years, and it should put on an impressive show online. It’s now visible in the images of several spaceborne observatories that monitor our star—the twin STEREO spacecraft and the Solar and Heliospheric Observatory (SOHO)—and should brighten as it makes what’s likely a suicidal run at the Sun.
