JULY 5TH - WL - AR2835 AR2837 AR2839

[paulastro]

I had a 25 minute window of a cloud affected sun from 7.10 to 7.35 this morning. 

AR2839 is rapidly growing according to spaceweather.com. In the 72ED I could see five umbral areas and two associated penumbral regions.  In AR2837 I could only see two pores, or possibly very small umbra.  It shows on my full disc shot, but you'll have to look very carefully to find it. I've attached a spaceeweather illustration below my pics to help locate it.

The single frame was taken with the SW 72ED and Olympus E-M5 Mk11 at 7.33 am, 1/250 sec at 250 asa. Also a crop of the same frame to show AR2835 as edges closer to the limb.

Brilliant Paul well done. Thanks for sharing.

Very clear shot, Paul, thank you! Do you use an extra green filter or is it the solar film that gives them the green colour? 

My single images with 127mm SW  Mak are usually of much lower quality and I have to resort to lucky imaging and stacking to get sharp results. 

I had a quick session around 9am and the seeing was mediocre but I'm glad to catch the departing 2835.

Thanks Nik. The green is not from the Baader Solar Film I use on the front of course, its from the two inch Baader Solar Continuum Filter I use screwed into the two inch T2 photo adapter I use between the scope and camera. I sometimes change the colour a bit when I do any processing, but sometimes I just leave it green.

Thank you! I will check the continuum filter at @FLO next time I indulge in accessories shopping . I will only need the 1.25inch version in my scope so should keep the cost down
