High levels of solar activity continue, today we had a big "Arboreal Prom" on the limb. Several of the active regions had some exellent interspot filaments too. Seeing was 1/5 and made getting a good image difficult!
Halpha:
Here is the full disk, using the Lunt LS100 and an Antares 0.5x focal reducer to get it to fit the chip.
View of proms only off the limb, several very nice ones to see today.
By removing the 0.5x reducer and inserting a Klee 3x shortie barlow, we can get close ups at 6x in reasonable detail. Those curved filaments mark the bourndries of magnetic flux in the sunspot.
Another less active region on the limb.
This is an amazing pile of small sunspots in a cluster. the fields are very complex here.
Another gorgeous group with active filaments.
Biggest group on the Sun today, is complex.
Proms. All these shots are at 6x, and the gamma of the camera is set for 1.50 to take in the extreme range of brightness between the limb and the faint proms. Compare to the disk shots above which were taken with a gamma of 0.40
Nice arch prom!
