   Soft gamma repeaters are rare sources of transient gamma ray emission
   and persistent X-ray emission; three of the four known are also X-ray
   pulsars. Recently, it has been found that both the X-ray flux and spin-
   down rate of SGR 1900+14 are not constant and the spectrum contains a
   thermal component. We propose to investigate these possibilities for
   SGR 1806-20, discover/confirm pulsations in SGR 1627-41, and confirm
   the fading of SGR 1627-41, and search for a thermal component in the
   SGR 1627-41 spectrum. Furthermore, we propose to search for proton
   cyclotron line features in the spectrum of both sources which would
   provide a confirmation of the magnetar model.
