Frank has been talking about imaging the Purbach cross for almost a year. For some reason we were under the assumption that it would be visible 4 hours before 1st Quarter. So we went yesterday and soon found out that we were too late. The cross is made up of the walls of the craters Purbach A, Blanchinus and La Caille. This morning i did research the times and we should have been there a lot earlier like 9:00 AM. however the moon did not rise until after 1:00. The next opportunity to image this would be on November 20, after 6 or 7 PM.
One of the things in looking for the cross made us search all along the terminator, where we found another one adjacent to the crater Pallas.
A very clear day today but a bit windy. The sun shows some nice activity today. A nice flare at 1512 and some nice prominences. The entire area around 1512 seems to be disturbed. I am adding a close up of this region.
