SOLAR FLARE: The strongest solar flare in nearly three months erupted from sunspot 1112 on October 16th. Remarkably, the M1-class event did not disrupt a huge magnetic filament passing right by the blast site. Future eruptions might, however, if this active sunspot continues to grow as quickly as it has in the past few days.

COMET 103P/HARTLEY AT ITS BEST: For backyard stargazers, the next few nights are the best time to see green Comet 103P/Hartley 2 as it approaches Earth for an 11-million-mile close encounter on Oct. 20th. Set your alarm for the dark hours before dawn, go outside, and look straight up. You will find Hartley 2 not far from the bright star Capella. Although the comet is barely visible to the unaided eye, it is easy to locate using binoculars and looks great through a backyard telescope.
