April 17, 2019: Solar Lunchtime

Recommended Posts

Got out the H-alpha scope over lunch, and admired the big AR once more. Due to hazy cloud only single stack worked well, but even in single stack I spotted a filament above the big sunspot which doesn't show up in the images I took this morning, although there is a disturbed area on the surface showing long filamentous detail early this

It definitely doesn't show the dark filament I spotted around 12:30. Several students dropped by to have a look, so it was a nice impromptu outreach session once more.

Will have another look but conditions are pretty poor here, job to see any detail.

Pyramid prom above the spot at  @ 2.00

Small tuft on the limb ahead of the spot @ 2.30

Hedge on opposite limb @ 10.00.

I haven't started prom imaging yet. :blush:
