Solar Activity 18 Jun

[brianb]

Another cloudy morning, clearing at lunchtime. The Sun is a little more active: the active region in the north east has been assigned the number 11082 and has a larger white light spot, though still not very big:

1318 UT. WO FLT 110, Lunt solar wedge, 2.5x Powermate, DMK21

1310 UT. Lunt 60mm, B1200 CaK diagonal, 2.5x Powermate, DMK21

Ha still shows interesting filaments in this region, but the plage area appears to be less active:

1250 UT. Solarscope 60, 2.5x Powermate, DMK41

The overview shows little other disc activity, but a couple of largish and numerous small prominences, which were bright enough to image by "one shot":

1240 UT. Coronado PST CaK, prime focus, DMK41

1247 UT. Solarscope 60, 0.5x focal reducer, DMK41

Here are closeups of some of the prominences - all taken with Solarscope 60, 2.5x Powermate & DMK21

NE limb, 1303 UT:

SE limb, 1301 UT:

W limb, 1256 UT:

SW limb, 1258 UT:

Transparency good but with some residual thin cirrostratus. Seeing moderate. Temperature 20C, wind N force 4.

Brian,

Just to say that I do really love looking at your images each evening. Was getting a little concerned this evening since the post was latter than usual. Please do keep them coming.
