Abstract
A summary of all available radio observations made during the 1991 June
campaign of the MAX
'91/Flare 22 program will be presented. The presentation will be
concerned primarily with
millimeter wavelength (BIMA and Nobeyama
) and centimeter wavelengths
(Owens Valley and
Nobeyama)
observations. Emphasis will be given to the question of
millimeter observations as a
diagnostic for Mev electrons in solar flares (gamma ray flares --- BATSE
and OSSE data),
millimeter emission occurring at the steep rise phase of hard X-ray
emitting electrons (BATSE
data) and delay of millimeter emission onset and 25-100 Kev X-rays
(BATSE data). Implications
of these results for generation of millimeter emission and particle
acceleration process will be
discussed. The Nobeyama
data consist of non-imaging patrol observations
at several frequencies
in the frequency range 1--80 GHz, and Owens Valley data were obtained
using the frequency
agile interferometer in the frequency range 1--18 GHz. Light curves and
spectral information of
the most energetic flares will be presented.
