A fresh morning with mostly clear skies, occasional lumpy cloud, cool with a strong northerly wind.

The Sun's disc is threatening to become spotless - I was just able to see the trailing spot of AR1039 in white light, and there was a faint patch of faculae, but CaK was needed to show it convincingly

2010 Jan 05, 1122 UT. 60mm @ f/16.7, Lunt CaK B1200, DMK41

Still just about there in Ha too

2010 Jan 05, 1130 UT. Solarscope 60 @ f/16, DMK41

But there was nothing else of any significance on the solar disk.

Proms, however, were located at all four "diagonal quarters"

2010 Jan 05, 1141 UT. Solarscope 60 @ f/32, DMK21

2010 Jan 05, 1138 UT. Solarscope 60 @ f/32, DMK21

2010 Jan 05, 1139 UT. Solarscope 60 @ f/32, DMK21

2010 Jan 05, 1133 UT. Solarscope 60 @ f/16, DMK41

Transparency good, seeing fairly poor, some smearing & significant boiling.
