Additional Information

Take off at 1620 UTC. ER-2 landed at MSN at 2000 UTC. ER-2 underflew portion of ADEOS satellite (IMG turned on) over NE/SD
region. Overpass at 1733 UTC. Overpass track between 43:40N, 97:40W to 39:50N, 99:00W. ER-2 didn't arrive at first checkpoint until
1736 UTC because of extreme headwinds at 50mb. Sky conditions during overpass were cirrus at northern end and apparently clear in
southern 3/4 of overpass. Pilot broke off satellite underpass about 35mi from southern endpoint. Surface appeared snow covered, with
amounts decreasing toward the end of the track, during the underpass of the ADEOS. Overpass of SSEC at 190530. UTC was cloud free.
All ground instrumentation operative during SSEC overpass.
Port 3 data appears degraded at start of flight. Data quality increases as flight proceeds, but again degrades
toward the end of the flight. Probably a result of a "soft" port 3 dewar; in other words low LN2 pressure.
