Dear all,

today I had a look at the GONG H alpha network monitor (http://halpha.nso.edu/) and figured out that the filaments of the past week have now reached the solar limb and at least the final one of it appeared as wonderful set of prominences. On my left/right-mirrored sketch this is the one in the lower left sector - if I consider the 5 hours difference of daytime compared with the previous sketches correctly. So, here's the sketch:

 

Telescope: Lunt LS 50 THa B600 PT
Eyepiece: Celestron X-cel 10mm
Date & Time: June 14th, 2019 / 1500-1530 CEST
Location: home terrace, Dusseldorf region, Germany
Technique: natural vine charcoal on white Hahnemühle Ingres mould-made pastel paper
Size: 24x31cm

Clear (and sunny) skies!

Achim
