Walking on the Moon

March 15, 2017: First H-alpha lunch session of the year

Recommended Posts

I have at last been able to point my Coronado SolarMax-II 60mm DS at the sun during lunch. I had expected an almost blank disk, but lo and behold, a sizeable filament graces the disk just south-west of centre. Another, fainter filament is to its west, and a small but quite dark filament can be seen northwards. The western limb shows a couple of faint proms, but the eastern hemisphere is much more quiet. There is a very faint and rather small prom in the north-east, and there are one or two thin filaments and not very active plage areas nearby. The south-eastern disk is rather blank.

Still, glad to have caught some H-alpha rays once more
