Query: Inverse Compton X-ray Flare from GRB Reverse Shock   We study synchrotron self-inverse Compton radiation from a reverse-shocked
fireball. If the inverse Compton process dominates the cooling of shocked
electrons, an X-ray flare produced by the first order Compton scattering would
emerge in the very early afterglow phase, with the bulk of the shock energy
radiated in the second order scattering component at 10-100 MeV. The dominance
of inverse Compton cooling leads to the lack of prompt optical flashes. We show
that for plausible parameters this scattering process can produce an X-ray
flare with a relative amplitude change by a factor of several. Flares with a
larger amplitude and multiple X-ray flares in a single event are likely to be
produced by another mechanism (e.g. internal shocks).
