Details of the balloon flight

Balloon launched on: 9/26/1989 at 14:16 utc
Launch site: Scientific Flight Balloon Facility, Fort Sumner, (NM), US  
Balloon launched by: National Scientific Balloon Facility (NSBF)
Balloon manufacturer/size/composition: Zero Pressure Balloon N29I-8/8/8/8T-28.40
Balloon serial number: R28.40-3-115
Flight identification number: 274N
End of flight (L for landing time, W for last contact, otherwise termination time): 9/27/1989 at 17:59 utc
Balloon flight duration (F: time at float only, otherwise total flight time in d:days / h:hours or m:minutes - ): 23 h
Landing site: 11 miles NW of Gallup, New Mexico, US

The balloon was launched Fort Sumner, New Mexico on September 26, 1989, reached the float altitude of 36 km at 11:05 MDT and began a gradual descent at 12:35 MDT on September 27.

The flight was terminated at 14:26 MDT.

The spectra obtained during the flight were taken mostly with the telescope pointing to 15º in geographic azimuth, corresponding to an average sampling latitude of 37ºN with the later afternoon scans on September 26 pointing to 188º corresponding to an average sampling latitude of 31º N.

No data were recorded from 4:30 to 8:01 because of a telemetry problem.
