A rare apparition during this quite period, don't hesitate to have a look.

Thank you for that sketch! I looked at the sun a few day ago and saw nothing but a white disc.

And because I know that some of you like the comparison, here a photo made by a friend of mine at the Bauduen Observatory one hour and a half before my sketch.

Made via a similar refractor, we can see that our eyes are not as affected by the turbulence than the cameras.

Michel,

 

 

Very nice sketch of these spots.

If the sun ever popped out here I would likely faint and then when I stand back on my feet get a scope and filter and have a look.waytogo.gif

Michel,

 

This beautiful solar sketch warmed me up with that fine color.

The weather folks tell me I might get to see the sun tomorrow.

Nice cascade of sunspots you are tracking here.
