The Dutch Observatory

Here is the image mentioned in the previous blog.  Tom Faber explained it very well:  “Looks like you got both sundogs (left & right of the sun). Faintly visible is the 22-degree halo. The bright one above the sun is the upper tangent arc. Faintly visible on the left… extending from the sun and through the left sundog is part of the parhelic circle.  See: http://www.atoptics.co.uk/halo/common.htm  ” Thanks for the info and link Tom.

Frank and I did image the Sun again today.  However, the Ha imaging got cut short because the light clouds became too much.  This gave opportunity to make a nice image of the sun with some atmospheric phenomenan (see the next blog).  Here the CaK  image with AR1120 .
