There were several proms on the solar limb that morning but these busy proms on the eastern limb seemed to be the most interesting to me. Some of the magnetic field lines around AR 1283 stood out for several seconds in good detail so I sketched them in with pencil over the pastel. That's why they appear a little shiny as pencil does that when used over pastel. Fibrils in the suns chromosphere line up along magnetic field lines giving up secret invisible information about their shape and extent of some of the magnetic activity in the Active Regions.
Obviously I am re tuning and re focusing the telescope constantly to capture all these features on the same plain , on a piece of paper. The sketch is CD size.
