Description:

The 10-1030A impulsive solar flux enhancements of solar flares during the ATM-SKYLAB missions are presented. The extreme-ultraviolet (EUV) enhancements were observed via sudden frequency deviations (SFD), an ionospheric effect caused by the enhancement of ionospheric photoionization produced by EUV bursts. The SFD measurements were made at Sacramento Peal Observatory; Boulder, Colorado; Leicester, England; Huntsville, Alabama; and Hawaii. EUV bursts are reported for the period April 1, 1973 to February 8, 1974, which includes several solar rotations before the first manned mission of ATM-SKYLAB. Compared to SFD observations from September, 1960 to July, 1970, the ATM-SKYLAB missions were periods of low solar activity when no large SFDs occurred. However, several medium sized events did occur with quasi-periodic or extensive fine time structure.
