I am thankful for the unseasonable weather and imaging i have getting. This is shot with my super high speed camera. If you pay attention to the sunspot penumbra you will see a little worm like appendage retreating into its core. Also notice the pulsating center. Captured at 500fps. and the rest of the film captures that larger fibril get sucked back down the drain. .
Last week I recorded a calcium limb surge. Later that night I discovered another user in the world on astrobin (Warren Spreng) who had captured the same event in hydrogen alpha at nearly the same focal length. The was an incredibly rare occurrence. I merged our two captures together, and this is the result. Red is the hydrogen alpha data, blue is the calcium data. I do believe this has a "one in a billion" capture odds, and few(if any) amateurs have ever been able to share and merge this type of time-lapse data. Enjoy!
