Develop and Implement Techniques to Predict Solar Activity and Its Geophysical Effects

The solar-geophysical data base previously assembled for the period January 1, 1955 through February 28, 1968, was extended to October 31, 1969. X-ray burst data were added to the base; 2-12A for the period July 3, 1966 through August 12, 1969 and 1-8A from March 13, 1968 through August 12, 1969. An...

Description
Summary:The solar-geophysical data base previously assembled for the period January 1, 1955 through February 28, 1968, was extended to October 31, 1969. X-ray burst data were added to the base; 2-12A for the period July 3, 1966 through August 12, 1969 and 1-8A from March 13, 1968 through August 12, 1969. An objective technique was developed for predicting the duration of the largest short-wave fadeout event (SWF) expected to be associated with a sunspot group tomorrow. An unsuccessful attempt was made to develop techniques for predicting 2-12A X-ray burst decay time once the burst has started. Equations were developed for predicting the geomagnetic index a(p) from 3 through 24 hours ahead. Future work is outlined. All of the above is directed to assisting AFCRL in its program to improve the operational forecasting capabilities of the Air Weather Service Space Environmental Support System (SESS). (Author)
