Conditions were surprisingly good when I imaged active region 12526, so much so pretty much all the frames I took in the sequence were good enough to make an animation from. This spans some 15 minutes of real time on the sun and is made up from 20 individual frames. The plasma dances round abundantly throughout the image, but of particular interest are the running penumbral waves, pulses of energy passing through the penumbral and super penumbral filaments at between 10 and 50 km/sec. Taken with the Airylab HaT at 4.4m focal length with a Daystar Quark and the PGR Blackfly GigE IMX249 camera.
Not much happening on the sun at the moment, just the single spot and active region AR12526 mid disk, and some filaments. Even the prominences are all small at the moment. Taken with the triple stacked 40mm scope at 700mm focal length with the PGR Blackfly GigE IMX249 camera.
A close up of this rather quiet active region with the HaT. The day was dominated by predominantly cloudy skies, with occasional fleeting gaps. This was about as good as it was getting, but nice to see the spot!
Any sunshine was quite sparse on Easter monday, but I did manage a few images late in the afternoon. The seeing really wasn't up to using the HaT to it's full potential, but it does get some nice image scale on these smaller scale features as we move into solar minimum.
Todays full disk in Ha was looking quite nice, with plenty of detail mid disk in the northern hemisphere and new double spotted active region AR12524 just appearing on the eastern limb giving us something to look at in the days ahead. Taken with the 40mm triple stack at 700mm focal length with the PGR Blackfly GigE IMX249 camera.
The sun was low and the transparency poor at 5pm this afternoon meaning I really had to lift the gain on the PGR Blackfly camera, but this disk came out ok. AR12524 that has appeared on the north eastern limb is a real monster of a spot, and weather permitting should be very photogenic in the days ahead. Taken with the homebrew CaK filter and the 40mm scope at 700mm focal length.
The evenings and mornings are really starting to stretch out now; it was nice to be able to get back from work this afternoon and be able to observe the sun with a bit of altitude in the sky. I got the triple stacked 40mm Coronado scope out and for a while it was just nice to stand and relax and look through the eyepiece. With clouds scudding by I decided to get a disk to get a record of what our star looked like today. Taken at 700mm focal length with the PGR Blackly GigE IMX249 camera.
