Solar Activity 20 Jun

[brianb]

Only a short sunny interval today, and with pretty wobbly seeing too, but I did (just) manage to image the two interesting bits of solar action.

AR 11082 is just about on the meridian, consisting of a pair of small but well formed spots and a few pores, including a "extra" group trailing it by some distance:

1132 UT. WO FLT 110, Lunt solar wedge, 2.5x Powermate, DMK21

CaK shows how the "followers" are embedded in the same plage. (Note the scale of this image is smaller!)

1141 UT. Lunt 60mm, B1200 CaK diagonal, 2.5x Powermate, DMK21

The AR is also interesting in Ha, with small bright flare-like points; surrounding filaments persist, though the long snakelike one extending to the south west has vanished:

1049 UT. Solarscope 60, 2.5x Powermate, DMK21

Prominences are genearlly small and faintish, the best action being on the east limb:

1054 UT. Solarscope 60, 2.5x Powermate, DMK21 (three frame mosaic)

Finally, here are the CaK and Ha overviews:

1032 UT. Coronado PST CaK, prime focus, DMK41

1038 UT. Solarscope 60, 0.5x focal reducer, DMK41

Transparency good but with interference from coastal mist and uneven high level cloud (cirrocumulus). Seeing poor with substantial boiling. Temperature 18C, wind N force 3.

There appears to be a quickly forming new spot in the group - I've been watching, and it is really growing!
