A little solar activity this week

[davenn]

Overall this Solar Max has been pretty disappointing. But occasionally the Sun as shown brief bursts of good activity
over the last week, and for a few more days, there has been a large sunspot group traversing the solar face.
AR2403 is a massive spot group and one of the largest this solar max. But it hasn't been overly active in the flare production department. So far 6 x M class flares, the largest being a M 5.6

Here's a pic I took yesterday 25 Aug 2015
800mm ( 400mm and 2x teleconverter), f11, ISO 250, 1/250th sec exp and a full aperture solar filter
was a bit of an act to get the shot as the sun came and went behind the thick rain clouds

cheers
Dave

Nice photo.

Have you checked on any of the solar satellites to see if they've seen something?

hi you

I used to use that site, but their image quality sucks these days
I use this one instead ...
http://umbra.gsfc.nasa.gov/images/latest.html

so much better quality !

I download the Fe 171, He 304, magnetic, intensity and x-ray images daily ( each morning before going to work)

Have a database of images spanning back to the mid 1990's when SOHO first came online
and now more recently superseded by SDO ( Solar Dynamics Observatory) space craftDave
