We review some of the highlights of the COMPTEL measurements of solar flares. These include images of the Sun in &ggr; rays and neutrons. One of the important features of the COMPTEL instrument is its capability to measure weak fluxes of &ggr; rays and neutrons in the extended phase of flares. These data complement the spectra taken with the COMPTEL burst spectrometer and the telescope during the impulsive phase of flares. We focus our attention on some of these general capabilities of the instrument and the latest results of two long‐duration &ggr;‐ray flares, i.e., 11 and 15 June 1991. ©1996 American Institute of Physics.
