Hazy skies contributed to a bit of background glow on some of thursdays images, but I was pleased with how this prom shot turned out and the subtle detail within it, especially as it was taken with the new 60mm f6 scope. This was taken with a Daystar Quark and the PGR Blackfly IMX249 camera.
This has to be one of my favourite shots from Thursday and is worth clicking on to view full size. The seeing must have been playing ball for this image as got a lovely feathery edge to the Sun, along with some nice small scale detail in the prominence. Tenuous filaproms grace the surface too - these clouds of cooler plasma held aloft by magnetic fields. This shot was taken with the 60mm f6 scope along with a double stacked Daystar Quark and the PGR Blackfly IMX249 camera.
The sun is certainly getting quieter as we approach solar minimum, but that doesn't mean nothing is happening on our star, things are just smaller scale. This shot taken with the ED60 and double stacked Quark shows this well, with the small remnants of the old active region in the left of the picture, and a particularly small prom on the limb. I like the field of view this setup gives for this sort of thing.
Despite the clear blue skies the seeing wasn't up to the resolution of 8" aperture with the HaT, I shot a number of images and these are about the best that came out. Taken with a native Quark and PGR Blackfly IMX249 camera.
2 solar rotations ago at the start of February the winter sun was graced with the sight of an active region yielding a number of spots. A rotation later it emerged on the solar limb as nothing more than a region of plage. On it's second rotation it took a bit of rejuvenation and for a few days following some minor flaring very small spots briefly appeared. In calcium wavelengths this bright plage is easily seen, however in Ha wavelengths it can be see a region of churned plasma with a central dark filament forming the boundary between the opposing magnetic field lines of the ex-active region. This shot was taken with the 60mm f6 ED60 scope and double stacked Daystar Quark along with the PGR Blackfly IMX249 camera.
It was a case of look carefully on the sun on 5th April. At first sign there is nothing happening, but look closer and there are a number of very small filaments all over the face of the sun. The clouds of cool plasma are held aloft above the suns surface by magnetic fields. Proms were in a small scale and also short supply. Taken with the double stacked Lunt 50 and the PGR Chameleon 3 camera.
Finally some clear skies, and I must have forgot how to use the 40mm CaK scope as I did an awful attempt at focusing on this disk. All pretty quiet apart from the relic plage from our active region from a few rotations back visible mid disk. Taken using the home brew CaK filter and PGR Chameleon 3 camera.
