Giant Sunspot Group - AR 2192

A giant sunspot group, AR2192, has formed on the sun again, and the group is now larger than the largest sunspot group we saw last year, making this the biggest sunspot group in the decade. AR2192 - 500mm Samyang Mirror Lens, Baader Solar Filter If you would like to know how big this really is, have a look at this image done by Paul Floyd at nightskyonline.info Copyright - Paul Floyd / nightskyonline.info The images below show my own images comparing the previous holder of the largest sunspot group of the decade that erupted last year: The group has caused several flares already, but there hasn't been any coronal mass ejections. A coronal mass ejection would pretty much guarantee that there would be massive auroral activity.

Lightening Photography

I have not been able to do any decent astrophotogaphy sessions recently. The rains are here and here comes the lightening shots. I'm fascinated of how it always strikes over the sea. All photos were taken with a 30s exposure F8.0 and F5.6 on a tripod. That actually makes it easier to capture lightening. You don't really have to do anything. The downside is that if there is some sort of ambient lighting, then your photo is likely to get washed out. You can step around this problem by having smaller exposure times.
