Comet C/2007 W1 Boattini in STEREO
However, Boattini is currently in the field of view of the STEREO Secchi H2a camera. It won't be there for long, but it looks pretty good as it speeds along.
Comet Boattini is brightening more rapidly than predicted, if it keeps this up it will be visible to the unaided eye relatively easily in late May - early June (provided you have dark skies of course, and all you will see is a fuzzy dot). Currently, the waxing Moon makes Boattini hard to see, but after May 21, with the Moon rising later, it will be time to start viewing this comet again. It may get as bright as magnitude 3.5 - 4 by mid June, although it will be fairly low to the horizon when the sky is dark.
