The Sun is becoming more blank each month, and as we approach a still distant solar minimum - which may be one of the deepest in recorded history - we can still see an occasional sunspot and prom. Today we had a nice small group on the limb, and a large reptile shaped prom hovering on the same limb as well.
Lets start with the full disk, with the .5x Antares focal reducer. The nearly blank disk has one active group, and a filament seen dimly above it.
The view however improves is we increase the gamma to 150 and brighten up the scene a bit. The large iguana prom is on the right side.
View with 3x Klee barlow shows nice detail on the active region, despite the poor seeing of 1.5/5.
In the Red Wing of Halpha, we can also see a few Ellerman bombs around the spot as tiny white points. These are micro flares.
3x view of the big prom!
