Keep an eye out for Comet Holmes, it might brighten again...even this month.
I don't think it will brighten one million times like it did in October
but there is a good chance that it may brighten 1,000's of times
(7-8 Magnitude increase or more) this month; it did so back
in January, 1893.
So if you have good viewing conditions, it may pay to keep a telescope
on the comet.
Elementary, dear Watson!... Elementary!...
