The Sun 26-9-08 - Nice proms plus last of AR11002

After a foggy morning the murk lifted to reveal a cloudless sky this afternoon. The small active area that produced the eruptive event this morning could clearly be seen in the east. AR11002 is right on the west limb now and could hardly be seen in Ha, but was quite clear in CaK light. The proms in the north west formed a fine parade of hedgerows, small arches and flames. Normally I wouldn't recommend using a 5X powermate on the PST as the results are usually pretty ugly, but I had another go today and the proms, while bloated, are not too bad considering the high magnification (see last two images below) - this is pretty much at the limit of what the PST can resolve.
