Sunspots on the Edge

Sunspots on the Edge

Active Region 1027 on October 29th, 2009
Sketch and Details by Fred Burgeot

* object : solar spot 1027.
* location : Vendée, France.
* date : 29/10/2009 at 14H15 TU.

Sketch made with graphite pencils (2H to 4B) on white paper. The telescope used is a 16″ Newtonian, equiped with Baader Astrosolar filter, magnification 175X with binoviewer.
It was made during afternoon, when the seeing conditions are currently better than in the morning.
Because of the proximity of the edge, a bright zone appears surrounding the spot group itself.

Best regards,
Fred Burgeot.

  1. This is a very impressive and detailed drawing of the unecpectedly active sunspot group.

    I’d like to mention that the correct number of this group ist 1029, not 1027.


  2. Fred,

    Fantastic sketchwork! One of the best white light sketches I’ve ever seen.

    Btw, I’m sure you meant to type AR 1029 for this sketch done on 10/29.

    Looking forward to more,
