This rapporteur paper addresses the sessions SH 1 Sun and Corona (SH 1.2 - SH 1.7) and SH 2 Transient Phenomena in the Heliosphere (SH 2.1 - SH 2.4) of the 30th International Cosmic Ray Conference (ICRC) that took place at Merida, Mexico during July 3 - 10, 2007. Session SH 1 includes solar emissions from energetic photons and electrons to solar neutrons, and the acceleration and transport of energetic charged particles at the Sun and in interplanetary space. Session SH 2 covers transient phenomena in interplanetary space and includes the effects of coronal mass ejections, corotating and merged interacting regions, and travelling interplanetary shocks.
