		<Description>

			AR 12135 SNS on umbra with SOT

128 repeats of OBSID 3800011454  -  Very large sit-and-stare 0.3x175 1s  Si IV   Mg II h/k Deep x 15

IRIS roll: 0.0 degrees

IRIS planner pointing: (-29.0 arcsec, 124.0 arcsec)

OBS duration: 4311.0 seconds = 128 repeats x 33.7 seconds/repeat

OBS data volume: 652.0 megabytes = 5216.4 megabits = 4311.0 seconds * 1.2 megabits/second
