The Sun 15-3-09 Two small active regions through the murk

Although certainly sunny the weather wasn't great for imaging with no real blue sky on view, just a spread of milky white thin cloud and haze. I thought imaging would be hopeless today but I had a look on the laptop via the DMK41 camera and was surprised to see some detail on the surface in the form of two very small bright patches of plage marking two emerging flux regions in the north and north-west. The main prominences were on the SW limb, a long fringe of low complex arches and hedgerow types which all appeared very faint. Exposure times were very low to compensate for the poor visibilty and gamma/gain adjustment was tricky. Even so I was quite pleased to pull some decent shots out of the murk with the two flux areas showing clearly and the proms looking very detailed for just 700 frames with 230 stacked. All pictures taken with PST and DMK41.
