In case you haven't heard, next week (just after the total lunar eclipse that I am not longitudinally privileged to witness) a sungrazing comet is going to graze the Sun. According to the following article, we can watch the SOHO observations as-it-happens:
Sun-grazing Comet Lovejoy flies by the Sun
I was really impressed in this article when they said that at top speed, these sungrazing comets are moving at more than a million miles per hour.
This picture is of Ikeya-Seki, mentioned in the article. Comet Lovejoy is not expected to be this bright; but we can hope.
