  "body": "Dear Colleagues:\n \nThis note is to inform you that, under the aegis of our HST AO-9 program,\nwe have requested observations of GRB 010222  (GCN 959) with the Hubble\nSpace Telescope and the Chandra X-ray Observatory.  This burst with a\nbright optical (GCN 962, 963) and radio (GCN 968) afterglow appears to\nbe particularly well suited for detailed studies of the afterglow and\nthe circumburst medium.\n \nThe Hubble observations involves six visits:  STIS/NUV-MAMA (Feb 26),\nWFPC2 (Feb 28, March 9, March 15-19, TBD, TBD). In addition, a 30-ksec\nACIS Chandra observation is expected to be conducted on March 6.\n\nWe encourage parallel ground based observations of this burst so that\nit will become a very well studied afterglow.  We will be supplementing the\nHST and Chandra observations with detailed multiwavelength observations\nat facilities to which our group has access (e.g. Keck, Palomar, MDM,\nHET). In the radio, we are undertaking observations with the VLA, JCMT,\nIRAM, Ryle, OVRO and Nobeyama.\n\nShri Kulkarni, Titus Galama and Fiona Harrison on behalf of a large\ninternational GRB collaboration.",
