SN2020jfo in Galaxy M61 still visible after 170days

I requested a new picture of M61 with the COAST C14 telescope on Tenerife. Comparing this pictures with previous pictures of SN2020jfo in May (my picture with TAL200k) and those one made with COAST in July, it seems to me the supernova is still visible. This time the M61 picture was much better then the previous one earlier this month, so comparing was much easier. See also my previous blog.



Sunspot AR2781 and Helioviewer

With support of Helioviewer I was able to define P and B0 of the Sun :

P is the position angle of the north end of the axis of rotation, measured positive when east of the north point of the disk and 
Bo is the heliographic latitude of the centre of the sun disk.



Sunspot AR2781 ND3.8, Solar Continuum & IR Cut filter




Around midtime the clouds disappeared making it possible the take some pictures of the complex sunspot AR2781. The group is smaller then earlier thus week but still a huge complex sunspot group.


The picture is combination of two pictures :
Nikon D7500 - TAL200K f/8.5 ND3.8 IR & Cut filter
Nikon D7500 - TAL200K f/8.5 ND3.8 Solar Continuum & IR Cut filter
