Active Region 1164 Experimental Sketch 2 March 1 st 2011 Pastel and a craft needle on black paper PST 40 h alpha, 40 mm TVP eyepiece.
I observed Active Region 1164 between 10:46 UT and 11:30 UT. Once again I tried an experimental sketch, an attempt to figure out the best media and methods
to capture the sun in a sketch.
The sunspot group as a whole was more prominent even in h alpha at the tuning point where all other active elements were visible.
The main spot was clearly two spots close to each other with one having an elongated umbra. The penumbra for these two large spots was clearly visible when the PST was tuned to the point when only the sunspot group was visible.
Long dark clearly malleable filaments danced around the entire area while waves of fibrils curved and heaved their way through the solar chromosphere along magnetic field lines.
At 11:17 UT four brighter areas appeared close to the sunspots. In this sketch I removed material instead of adding it in my quest to achieve an accurate rendition of what I can see with my eyes at my telescope.
