Solar ACtivity 15 Sep

[brianb]

Another very windy day, dull morning but brightening up in the late afternoon with a few sunny intervals between light showers. Solar activity similar to yesterday.

1449 UT. Coronado PST CaK, prime focus, DMK41

1455 UT. Solarscope 60, 0.5x focal reducer, DMK41

The "sail" prominence which has adorned the NE limb for a few days has now rotated fully onto the disc as a "bruise" type filament:

1502 UT. Solarscope 60, 2.5x Powermate, DMK21

There are still lots of filaments in the north western sector:

1501 UT. Solarscope 60, 2.5x Powermate, DMK21 (two frame mosaic)

One of these projects over the limb, forming a "filaprom":

1509 UT. Solarscope 60, 2.5x Powermate, DMK21

AR 11106 is little altered:

1459 UT. Solarscope 60, 2.5x Powermate, DMK21

I was unable to image this AR in CaK or white light due to interference from cloud. I would also like to have imaged the prominences on the east limb.

Last but by no means least, there is a spectacular prominence on the SE limb:

1515 UT. Solarscope 60, 2.5x Powermate, DMK21

Transparency moderate with interference from showery clouds blowing in the strong wind. Seeing moderate. Temperature 15C, wind NW force 6.

Another lovely set of images in wild conditions Brian. The CaK is especially sharp in this set. Nice filaments on the NW sector. A real sense of 3D with those.

Thanks for the cracking images

I do appreciate your images Brian

I know it takes time and effort to upload and share images

I have not used my Ha rig for weeks
