[QUOTE="Binastro, post: 3182489, member: 111403"] . At about 1330 UTC today I saw a sunspot with protected unaided eyes. There was quite extensive Cirrus cloud at 25,000 feet, some of it was quite thick and other parts very tenuous. There was high pressure and it was about 12°C and a nice sunny day. I estimated the size of this sunspot as 40 arc seconds penumbral size. It was at the 10 o'clock position one third of the way from the limb to the centre disc. At 1024 UTC this morning it was at the 8.30 position. As the Sun moves across the sky it seems to rotate depending on the latitude of the Observer. I had no luck trying to project the Sun on the kitchen wall with either a 10×25 binocular or a 20×50 spotting scope handheld. The image was too unsteady and maybe not in focus. I think tripod mounted I would have seen the sunspot in the image projected on the wall. There have been almost no sunspots in the last 10 days although there was quite a bit of cloud so I couldn't observe the Sun every day. In a properly protected small instrument the sunspot is actually a large black sunspot with a small sunspot to its right and possibly other unresolved smaller sunspots. By March 20 this sunspot will be either on the other limb or just rotated past it. However, there maybe new sunspots visible on the date. This present sunspot may possibly become a bit larger as it moves towards the centre disc over the next few days, or possibly not. [/QUOTE]
