EquipmentThe Imaging Source DMK31AU03.as CCD Camera at Prime focus of my Lunt Solar Systems LS60THa w/B1200 & 0.5 Focal Reducer, mounted piggyback on my Losmandy G-11 and mounted inside my Skyshed POD
DescriptionI was shooting the Solar Disk with Sunsot Groups AR1528, 1529, 1530, 1532, 1533 and 1534 when a jet roared across the disk. I knew seeing was good that day, but didn't realize how good untiul the jet passed by WITHOUT leaving a contrail. The atmosphere was so dry it immediately absorbed the moisture from the jet exhaust leaving no trail.

LocationPommier Observatory, Portland, OR, USA
EquipmentTelescope:Celestron Compustar C14. Camera: Point Grey Research Flea3 Color. Best 300/1194 frames. Hydrogen-alpha filter, 1 angstrom bandpass. Three-inch energy rejection filter, rendering the system at f/51.
DescriptionA large solar prominence on the near side of the solar limb, left, is seen projecting into space and exchanging filaments and clouds of plasma with a large prominence beyond the solar limb, seen somewhat more face on, right. Together, they form an enormously large arch. Over time, several filaments and clouds of plasma could be seen passing from one prominence to the other along the arch and I was able to make a frame by frame animation of that from several video clips. Although hydrogen alpha solar images are often obtained as grayscale data, I shot this video in color in an attempt to convey the actual visual appearance of solar prominences through a hydrogen alpha filter. The data for the solar disk were de-saturated and then artificially re-colorized to provide contrast in appearance between the disk and the solar prominence arch.
