H-alpha Solar Animation

Blogged by Aurélie Le Fort Beunink on August 5, 2011 and tagged with Sample Images, Sun, Animation.

Lots of solar activity of late, attached are an animation and a collage of AR11260 shot with a 50mm aperture H-alpha filter/telescope and my workhorse DMK 21AU04.AS.

The time-lapse animation was shot over a period of 50 minutes at a cadence of 2 minutes[...]. give or take, as seeing allowed.

Along with the sunspot, a number of dark filaments are moderately active with minor flaring coming and going.

I've also included a collage of AR11263, 11261 and 11260, shot with the same filter/telescope and DMK 21AU04.AS.

Sunny skies!
