Weekly Solar Image 7-8-12

I love a nice clear day with no clouds in the sky, it usually means I can drag the telescope and the solar filter out for some solar observing. This is especially nice when it happens on a weekend, so that I can just go out on the back deck before the sun gets behind one of the many trees in the yard.

Doing these weekly images is a lot of fun, especially now that I have a way to magnify on a specific sunspot using my DSLR. Just like last week there is a big sunspot coming around the southeastern limb of the sun, sunspot 1520 with small sunspot 1519 right next to it. Above those two is a small, not very visible, sunspot 1518, and 1514, and 1513 turning away from the Earth’s view.

Sunspots 1513, 1514, 1518, 1519, 1520

Sunspot 1520 is the big sunspot spanning a distance of 127000 km (you can fit 10 Earths inside of this sunspot) from end to end. This sunspot harbors the energy for M-class flares, so I’ll be watching for the possibilities as the week goes on, and maybe we’ll get a chance for auroras here in the Adirondacks. NOAA estimates an 80% chance of M-flares in the next 24 hours although so far 1520 has only produced the lesser C-flares.

Sunspots 1520 and 1519

All images taken with the Omni XLT 150 and Canon 350D. Full disk sun is 195 images stacked in Registax and post processed in Photoshop. Closeup of sunspot 1520 is 65 images using an Orion Variable Camera Adapter eyepiece projector giving me a magnification of roughly 183x.
