Three days ago March 28th 7:30 UT in the morning a friend of mine made this HAlpha photography :

OABProtu28032020_l.jpg


He made this photo (yes it's a photo undecided.gif ...) with a 60mm Lunt from the OAB : Astronomical Observatory of Bauduen (400 images - 50i/s)

 

Because of that image I was wondering if an active area will get up on the same position near the limb, and yes, today March 31st 7:53 UTC here's the 3 spot's group.

I'm just back from an early sun observation in white light, just before the announced clouds.

I made this sketch with a 150/f8 and objective filter,

 

Because of the position, 37° North this group belongs more than probably to the new group.

 

For your information, her's the sketching material I always use, you can see the metal erasing shield drawing template and the precise eraser I use often.

Clear and virus free sky to you all, and... stay in your observatory  !

Thanks you Michael!
I appreciate your good desires and your great sketch. Two days ago I was watching the Sun and of course the were not spots at all. I will try to follow these ones time permiting. I am based in Spain. Please please stay at your houses (best at your observatories!). This virus is extremelly infectous. Take care and one more time stay at home.

Michel:

 

Thanks for the sketch and the information.  Nice sketch.

 

I was observing the sun yesterday with both my PST and a white light filter on an 80mm ED/apo.  I saw two significant prominences with the PST but nothing in white light.  

 

If it's clear today I will see if I can see the sunspots in white light.

 

Jon
