   PR #   116
   SN1987A was a unique event recorded just after the launch of GINGA.
   Now, 6 years later, this observation will obtain the most sensitive
   upper limit to X-ray emission from the remnant and the possible
   central pulsar. The pulsar period can be in the range of millisecond
   or less, and the spectrum can appear to be very hard due to strong
   absorption by the supernova ejecta. (There is an informal report of
   possible detection of optical pulsation of 2.1 msec period recently.)
   Search for the pulsation will be a good test of fast timing. It is
   known that the region of LMC has diffuse soft X-ray emission. A few
   X-ray sources including the SNR N157B will be in the FOV. There could
   be stray light from LMC X-1 as well. $@ (J*******
