During the last couple of days AR 956 has grown from invisible to a giant many times bigger than the Earth, and is now visible to the unaided eye. Got this image today using the ETX 90mm and Toucam. It's made from 408 frames in Registax. This is a most beautiful group and I would urge you to have a look. Be careful to have a suitable filter or project the image onto a white card.  |

Excellent image John and I agree about the beautiful appearance of the spot. It is completely unpredictable! Glad you seen it with the NE also. What time was your obsv? Great stuff  The sky cleared beautifuly this afternoon so I managed a second visual observation of Active Region AR0956 between 13.05 - 13.30 UT with the 90mm ETX at X48. Using the projection method I simply held a folded sheet of paper away from the eyepiece and projected the Sun's image onto the page. This is the most simple form of solar observing one can do but it is very rewarding! 965 looked very active indeed and spanned a rich portion of the solar disk (several Earth diameters) and now a more productive distance from the eastern limb. The spot is a fragmented mess consisting of two main Umbrae. I counted between 24 - 26 spots/pores. Using a solar filter I could see the spot with the naked eye (my 54th naked eye SS) at the 11.30 position as a faint dark smear against a brilliant white disk. I could only glimpse it with averted vision but it was there nonetheless. I have a feeling 956 will blow anytime soon! Here are a few images for a little fun. The focus is poor as I was holidng the paper in one hand and the camera in the other in a breeze plus I could not see the camera's LCD screen due to the glare of the Sun...   |

Nice work John and Martin! Looks like 956 has potential to give us a bit of action - if it blows we have to hope it's at a time when it's clear enough and dark enough - we have now passed the end of astronomical twilight!
Clear skies,
Paul.
