IUE International Ultraviolet Explorer Observing Session November 1991

The IUE (International Ultraviolet Explorer) satellite telescope operation control center at NASA Goddard Space Flight Center, Greenbelt, Maryland, during an observing session during the night of November 17-18 1991. The target was the G1 V star HD 39587 χ1 (Chi 1) Orionis. The TO (telescope operator) is Tom Walker and the RA (resident astronomer) Martin England. The IUE was one of the most successful astronomical satellites, operating from 1978 to its shutdown in 1996, when it was still functioning, an interval far in excess of its planned minimum three-year lifetime. It produced ultraviolet spectra of astronomical objects in the overall wavelength range 115-330 nm (1150-3300 Å).
