Title: Multispacecraft hard X-ray observations of fine time structure in two solar flares

Journal Article · · Astrophys. J.; (United States)
DOI:https://doi.org/10.1086/160749· OSTI ID:6051809

Two solar flares occurring on 1978 December 3 and 4 were observed in X-rays > or approx. =100 keV by identical instruments on widely separated spacecraft operating in near-Earth orbit ( Prognoz 7) and interplanetary space (Venera 11 and 12). The data show clear evidence for fine time structure on scales down to 55 ms for the e-folding rise and fall times. Such data may be used to localize the emission region by the method of arrival time analysis.
