Solar Details: Sat 17th July 2021

[TakMan]

A whole month since my last solar imaging session

Set up by 8.20am (BST)

Basler '174' > Quark > TEC140 > Baader D-ERF.  AS!2 > ImPPG > Ps. Captured in Pylon.

All images, best 100 frames from 3000. Mono 12P, 110fps, Full disk images flat frame (bag) calibrated. 0.29"/Pixel. Guided by an Hinode Solar Guider.

Presented full size, warts and all (just stacking cropped) !

Closest (by UT/GMT time) GONG image first for reference.

Main Spot / AR2842, 8.21 BST, 6500ms

 

Disturbed region to the left of AR2842, 8.26 BST, 6500ms

 

Small spot below centre, 8.30 BST, 6500ms

 

Lower right disturbed region and small prom, 8.33 BST, 6500ms

 

New Spot / AR2844, 8.35 BST, 7500ms

Spaceweather have a piece on the above "High Latitude" spot - screen grab attached:

 

Large faint receding prom - upper right, 8.38 BST, 10,000ms

 

Before you go... for perhaps the more experience Quark imager.... what is the bright 'arch' artefact above the prom on the image above..? I can see it 'rotate' as I scan around the solar edge and the as I slew the scope to the opposite side, it disappears.... reflection...? Put a towel over the Quark/camera to check for light leaks... didn't remove it...

Anyway, still processing (and watching the WEC 6hrs of Monza race), from yesterday and pre-processing today's images (got out a tad earlier this morning to miss the heat of the day). Will add to this thread later then if any other data-sets prove successful.... 

More Added:
Large faint receding prom - upper right, 9.14 BST, 16,000ms (so blown the surface detail out!) / 62 fps

 

A close-up of those filaments (the inner two) at roughly 10.30/11 o'clock on the GONG image, 9.41 BST, 6500ms

 

Main Spot / AR2842, 8.46 BST, 6500ms (cropped)
