  The discovery of X-ray afterglows accompanying two short bursts from SGR
1900+14 is presented. The afterglow luminosities at the end of each observation
are lower by 30-50% than their initial luminosities, and decay with power law
indices p ~ 0.2-0.4. Their initial bolometric luminosities are L ~ 10^34-10^35
erg s^-1. We discuss analogies and differences between the X-ray afterglows of
SGR short bursts and short gamma-ray bursts.
