cotton ball sun - wow active region! 9/21/2020

[Kitsunegari]

I reside in the central great plains of the United States, and recently our west coast has been set on fire by rioters and arsonists due to civil unrest.

 

The smoke from these residential homes and forests burning, is delivered high into the atmosphere where it hit the jetstream and has traveled well over 1000 miles to blanket my sky.

 

While i can still take some images, it has greatly reduced my session quality at 393nm.      Naturally the smoke properties absorbes or reflects much of this wavelength.      The sun is very white in the sky in fact, white as a cotton ball in some areas.

 

 

However,  i am vigilant in my attempt to capture something out of the new active region.      Please be patient while this data is processed.  

 

 

 

 

 

First we have a look here at the paris meudon bass2000 spectroheliograph , which records its daily calcium k3 core full disc.    I have added an arrow to the tiny area that my scope is focused on at about 2400mm..

 

Full image disc citing goes to paris meudon observatory, with corresponding link to the wonderful and most vital French institution. http://bass2000.obspm.fr/home.php

 

 

Next from my telescope, operting with an explore scientific Firstlight 127mm x 1200mm achromat.  In the focuser is a Skybender tilt module with some calcium filters supplied by Apollo Lasky.   I am using a Meade 2x telenegative barlow in the eyepiece of the skybender, and a basler aca1920-155um cmos camera for recording.

 

 Look at those calcium ribbon's!  This is a rare capture, seldom seen since cycle 24, a decade ago.
