Images of Northern Hemisphere sunspot groups taken after 2300 UTC 14JN99 using a 10" SCT and 1/3" CCD color camera.  Artifacts in the images are unaccounted for and suggestions and comments regarding their presence would be appreciated.

"Jurassic Park" Sunspot
The sunspot is a northern latitudes group and was recorded at 22h 27m UTC on 25July98.  The image is recorded in correct / not reversed orientation using the 10"SCT and PSA 1/3"chip color camera.   The interesting thing about this group, besides its profile, is the appearance of parallel bars crossing the entire group from 10:30 to 4:30, as if someone had dragged a comb through the whole group creating streaks in the structure. I found this characteristic to be very unique.

Charles Shirk of Dayton, Ohio was imaging the Moon  with an 80mm f/5 refractor using a PSA color video surveillance camera from his home near the Dayton International Airport when an Emery Worldwide freighter flew through the frame.  According to Charles, the folks at Emery enjoyed the copy of this photo he sent them.
