Active Regions & Prominence | 656.28nm & 393nm | Aug 6th 2018

Post by MalVeauX »

Heya,

Wonderful clear skies this morning, but dreadful, truly dreadful seeing. I couldn't manage anything at large scale so I just stuck to smaller scales today. Very few prominences worth noting, a single grouping that is fairly big and interesting on the limb. The two active regions are still present and are easy to spot in several wavelengths, so white light has something to look at which is nice. No sunspots. Looking forward to cycle 25 as it may be slowly on its way which is exciting based on an active region that showed up the other day and decayed quickly in a region we typically don't see activity in during this cycle's minimum. Grabbed data in 656.28nm with a Quark and a masked ST80 operating at 60mm F6.67 and a focal-reduced (0.5x) 152mm F8 refractor (to drop scale, couldn't image at large scale). Grabbed data in 393nm with the ST80 for a quick full disc and the larger scale with the 152mm F8 refractor with a Skybender. The HA full disc is a mosaic made with the ST80 and Quark.

All great, Marty, but I particularly like the CaK results
