Solar Sunday: In Honor of Leonard Nimoy
Sunspot count 54 (SDIC) C-Class Flare Observed Live in H-Alpha

We talked about Leonard Nimoy at today’s Solar Sunday. There is no doubt that Star Trek is part of the amateur astronomy mind set. The common element of wanting to seek out and explore our universe, and of course imaging life out there is intriguing. And we amateurs get to explore and imagine with our telescopes. Just as appealing – is imagining Gene Roddenberry’s future – where there is no discrimination between a community of planets. Spock’s character brought that universe to life and Leonard Nemoy’s sensibility to the character endeared the minds of a staggering and still growing fan base that started 50 years ago. Many thanks Leonard for ensuring these ideals live long and prosper.

Sunday Solar had about 15 visitors today with many of them observing and talking about the sun for an hour or more. We counted 53 sunspots, 11 filaments (prominences), and limb prominences at moderately high power.  Below are some of the dedicated patrons!

For those of use who observed after 3PM in H-Alpha, we got to see plage (chomospheric brightening) around AR-2290 rise and brighten into a conical flare. The event lasted about 20 minutes. AR-2290 was located perfectly near the solar limb. We had begun to noticed that the plage seamed elevated 1-2 Earth diameters above the photosphere. We then noticed it formed a conical shape, brightening, and extending vertically to a height of 5 Earth diameters. AR-2290 has created about a half dozen C-Class flares over the last couple of days (link). This flare below was recorded just hours before our observations:
