Sun in HAlpha / CaK / White Light With Lunt LS100THa / Stellarvue - Zeiss SV80s + Lunt CaK filter or Baader Wedge Uploaded 3/2/12 Weekend Report For the weekend of February 25-26, 2012
Solar activity was subdued this weekend, with two moderate spot groups appearing with little chance of flaring or major activity. A few good proms appeared as well. A few solar shots for the first time from our Happy Jack observatory - Clear Creek Canyon Observatory at 6800 feet elevation revealed a higher level of contrast on the white light images especially than our normal 5150 feet site in Payson.

AR1423/24 appearing on the eastern limb. This close up is with the 5x Televue Powermate.

On the western limb, AR1422 is stunning surrounded by "facula".

These are with the new Lunt LS100 and a 2.5x Televue Powermate Barlow. A strangely disturbed region below

AR1423/24 in hydrogen light is surrounded by activity!

A very active non sunspot region in center, and on the limb is our disappearing friend - AR1422.

Sunday 26th

These images were the first solar images I have ever taken from our observatory in Happy Jack - Clear Creek Canyon Observatory. The day was quite windy, and seeing was 2/5. But the transparency was higher than in Payson and the solar granulation appeared more distinct. I cant wait to see what this site will produce when the seeing returns to its sub arc second normal conditions!

White Light

full disk overview. Note that AR1422 is now gone, and we are left with several nice small spots including AR1423. The entire disk is covered with the solar granulation seen very clearly here - that is not noise.

5x Televue Powermate Barlow close up of the largest sunspot on the left edge, with some smaller pores in the center. The many other close ups were trashed by the high winds.

The white web work seen all over this disk is the so called "Chromospheric Network". It is essentially the outlines of the outside periphery of the supergranules.
