  "body": "SGR 1806-20: Low frequency GMRT results\n\nP. Chandra (Tata Institute of Fundamental Research (TIFR), Mumbai),\nreports the detection of radio emission from the  soft gamma-ray repeater\nSGR 1806-20 with the Giant Metrewave Radio Telescope (GMRT) in the\n610/235 MHz bands for 1.16 hours on 2005 Jan. 04 (mean epoch approximately\n0949 UT). The preliminary flux densites for 2005-Jan-04.409 were:\n\n 608 MHz:  198.9 (11.9) mJy\n 240 MHz:  242.6 (14.9) mJy\n\nThe last digits in the brackets indicate 1 sigma error bars. She notes\nthat the power law index beween the two frequencies is: -0.21 (0.09). This\nindex is substantially flatter than the corresponding power law index\nreported in the higher frequency VLA observation on 2005 Jan 4.59 UT by\nCameron and Kulkarni (GCN 2934) (alpha = -0.74 at 1.4 GHz) or -0.61 (0.06)\nreported by Gaensler et al at the same time (GCN 2933). Further\nobservations with the GMRT at other low frequencies are also planned.\n\n[GCN OPS NOTE (06Jan05):  This Circular was delayed by 3 hours\nuntil the submitor could be added to the list.]",
