It took some time for the clouds to clear this morning so we didn't get to start until late, after 10am. The SSM showed the seeing wasn't great but initially there were some dips below 1 arc second so we set up the 6" SCT for some 540nm close ups. The first one AR3335 was quite good, the next two headed downhill, the remainders went to the bin! We then took a full disk mosaic in 393nm and finally started to take some Ha images. We only managed a full disk before some clouds reappeared.
Close observers of the Ha mosaic will notice there is an 8 minute gap between the first panel and the second panel. This is due to a new to us solar astronomy nuisance, anthropological seismic disturbances, otherwise known as road works. The back story is that the council have been digging up and working on our street for about 6 months and are now compacting a new surface with a vibrating roller which turned our scope into a seismograph :) With the clouds and the roller there was no point trying for any further images.
The sun certainly put on a good display for the winter solstice with 10 or more active regions and some impressive proms on the eastern limb.
