Abstract. The HXS and GRS detectors on Yohkoh observed the 2000 July 14, X5.7 flare, beginning at ∼ 10:20 UT, ∼ 4 m before the peak in soft X rays. The hard Xraysandγ rays peaked ∼3...
Correlation of Upper-Atmospheric 7 Be with Solar Energetic Particle Events (2007)
G. W. Phillips, G. H. Share, S. E. King, R. A. August, A. J. Tylka, J. H. Adams, ...
Abstract. A surprisingly large concentration of radioactive 7 Be was observed in the upper atmosphere at altitudes above 320 km on the LDEF satellite that was recovered in January 1990. We report on...
Source Regions of Major Solar Energetic Particle Events (1998)
Nitta, N. V., Cliver, E. W., Tylka, A. J., Smit, P.
We examine the source regions of the largest prompt solar energetic particle (SEF) events (J(sub proton)>10 MeV >100 pr/sq cm/s/sr) occurring between 1992 and 2002. We find that the 25 such events...
