The Sun 31-10-08 - AR11007 Appears!

AR11007 has appeared out of nowhere on the north limb today and is another SC24 sunspot group, the fourth this month! Looks like SC24 is well under way. The bipolar sunspots were easily visible in Ha and CaK light. There was also a small proto-AR close to the east limb which may develop in the next 24 hours. Proms were every small but there were some nice dark filaments in the north and south polar regions.
