20080315 Sun (very poor sky)

Today the sky is even poorer, I mean the seeing is really bad like 1/10, everything is very low in constrast, and the transparency is bad as well, like 2/10, and thus no meaningful detail can be acquired. At the same time, the sun is very quiet, nearly no prominences, and nearly no surface activities except a few short filaments, and some bright patches.

Telescope: Borg 45ED II
