[vsolj-alert 507] GRB991217



GRB991217

 本日またGRBが発生したようです。X線がよく出ているもよう?
 夕方の観測の都合のよい場所にあり、まだ何か見えるかも知れません。

BeppoSAX GRB Alert: GRB991217

On Dec.17, 04:12:20 UT a faint X-ray rich event with a marginal
detection in GRBM (GRB991217) was detected  by BeppoSAX WFC2.

  Preliminary coordinates from WFC are:
  R.A.(2000)= 345.867
  DEC (2000)= 0.228

  with an error radius of about 6'. The position error is the standard
  statistics+systematics, but the  satellite was in testing mode, so the
  estimate is very preliminary. For the  same technical reason an NFI
  observation is not being planned.
