Transit of Mercury
Reminder: Tomorrow morning (in the US) is the Transit of Mercury across the face of the Sun. This is a somewhat rare event and if your skies are clear be sure to check it out. Don’t ever look at the sun without proper protective filtering. Mercury will be too small to see with welder’s glass or eclipse glasses.
Also, remember that we have a Special Observing Award for the transit:

Good luck. Aaron
