Sketch created scopeside with black Canford paper, white Conte’ crayon
and pencil, white Prang watercolor pencil.
Temp: 24.4° -25.8°C, Humidity 74%-61%
S: Wilson 4 dropping to 1.5, T: below average
Clear to lightly scattered, breeze <7mph SE

Plenty of smaller prominences, concentrated on recordings of the four
most prominent areas. Very minimal surface details with respect to
filaments, ARs and plage. Chromospheric network was stunning.
Erika,
Beautiful gossamer rendering of the finest solar prominences, best appreciated when double clicked to the enlarged image.
