Morning here was dull but the Sun broke through after lunch - and, with the declination increasing, it was even possible to observe it after 2pm!
Lots & lots going on.
2010 Feb 18, 1406 UT. PST CaK, prime focus, DMK41.
AR1049 is conspicuous near the meridian in the southern hemisphere.
Monster prominences on south east & north west limbs:
2010 Feb 18, 1431 UT. Solarscope 60, f/5, DMK41.
Close up of AR1049 in red, white & blue:
2010 Feb 18, 1435 UT. Solarscope 60, f/16, DMK21.
2010 Feb 18, 1425 UT. 80mm refractor, Baader ND5.0 solar film & solar continuum filter, 4x Imagemate (f/24), DMK21.
2010 Feb 18, 1449 UT. 60mm, Lunt B1200 CaK diagonal, 3x barlow (f/25), DMK21.
The plage visible on the east limb is a "new" active area, it contains a spot which was found during processing of high resolution CaK images:
2010 Feb 18, 1451 UT. 60mm, Lunt B1200 CaK diagonal, 3x barlow (f/25), DMK21.
The major prominences were imaged twice with my Solarscope 60 & 2x barlow, DMK21 camera, showing some evolution:
1443 UT
1503 UT
1440 UT
1505 UT
Transparency very good but with some drifting cloud. Seeing very variable, good at times but poor at others. Temp +6C, wind NW force 1-2.
Lots & lots going on.
