Watch Live as a Kreutz Sungrazing Comet Approaches the Sun
March 14, 2012
A few days ago Vladimir Bezugly noted a new comet in images taken with the SWAN instrument on the Solar and Heliospheric Observatory (SOHO) satellite. The comet was located within 20 degrees of the Sun and appeared to be on a Kreutz sungrazing orbit that will take it within a few solar radii of the Sun’s surface. Unfortunately no ground-based observations were possible.
