Next: Observations and Analysis Up: The Second EGRET Catalog Previous: The Second EGRET Catalog . ... The first EGRET catalog ([ Fichtel et al. 1994b ]) covered Phase 1 of the Compton Gamma Ray Observatory (CGRO) viewing program which began shortly after launch of the observatory on 1991 April 5 and ended on 1992 November 17. ... No additional solar flares were seen during Phase 2; therefore, the first EGRET catalog summary has not been updated in the present work. ...
