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.
Today I decided to get out in the heat, and do some solar images. I couldn’t resist going out seeing how many sunspots there were, and how nice of a cluster there was in the southeast limb of the sun. The main thing that really got me out was a notification of geomagnetic activity.
I had a bit of difficulty achieving focus for some reason, it seems to be hit or miss when I go out and get images of the sun. I was able to pull together a decent stack of the sun to show off the sunspots.
Sunspots: 1512, 1513, 1514, 1515, 1516
This image is 100 images stacked in Registax, and post processed in Photoshop.
This next image was me using my new Orion Variable Universal Camera AdapterI got on Amazon. I used my 12.5mm eyepiece in the projector to get this magnification. The quality of this isn’t quite what I was going for, but overall I’m very happy with the way this came out for my first use. Sunspot 1515 is the largest one on the face of the sun at the moment, and I had to try my hand at getting images of it.

This image is 50 images stacked in Registax and post processing done in Photoshop.
Starting yesterday afternoon into today there has been a geomagnetic storm caused by large sunspot 1504. The aurora reached storm level as this sunspot crossed the face of the sun, and blasted 2 CME’s towards Earth.
Sunspots: 1504, 1505, 1507, 1508. 6-16-12
This image of the sun is 100 images stacked in Registax with some post processing done in Photoshop. Images were taken yesterday (June 16, 2012) afternoon, but I ran into some issues when stacking.
Today we had some clear skies for a while and I decided to get out with the solar filter again and grab a few images. Below is an image of the sun taken with a white light solar filter, canon 350D, and an Omni XLT 150. The sun isn’t highly active at the moment, and there is a small chance of any solar flares, or aurora. Sunspot 1492 did blast off a CME towards Mars on May 27th, but no signs of anything coming our way.

Notice in certain areas how you can see lighter sections of the sun around the sunspots. They were very hard to see through the eyepiece, but definitely became more visible after taking images and uploading them onto the computer.
This is 60 images stacked and edited in Registax. I adjusted the sun to be angled roughly the way it would be from the ground in Gimp.
Unfortunately clouds came rolling in shortly after I took these images. I was watching the clouds slowly cover the sun through the telescope. It was quite an interesting sight to see. Hoping for clear skies in the not too distant future. Especially for the Venus Transit on June 5th
. I’ll post more about that a few days before as a reminder.
