Abstract Observations of the galactic background radio emission at a number of frequencies between 2.75 MHz and 0.51 MHz were made in association with the Spacelab-2 plasma depletion experiments to test the concept of making low frequency observations through an artificially created window. Following the Shuttle OMS burn at a time when foF2 was 1.99 MHz, a decrease in the maximum ionospheric electron density of approximately 30% occurred. The first observations of the radio emission at 1.704 MHz at high galactic latitudes with good angular resolution (25 degrees) were made during this event.
