Chandra on behalf of GMRT observatory reports the detection of\nradio emission from the SGR 1806-20 with the Giant Metrewave\nRadio Telescope (GMRT) in the 235 MHz band (resolution 12\"-18\")\non the  following dates:\n\n 240 MHz:\n\n 2005 Jan 4.41 UT:   465.8 +/- 28.3 mJy\n 2005 Jan 6.38 UT:   462.3 +/- 29.1 mJy\n 2005 Jan 7.25 UT:   231.0 +/- 20.2 mJy\n 2005 Jan 8.24 UT:   249.6 +/- 17.1 mJy\n 2005 Jan 9.26 UT:   175.5 +/- 19.8 mJy\n 2005 Jan 10.16 UT:  155.4 +/- 08.5 mJy\n 2005 Jan 26.26 UT:  103.9 +/- 31.0 mJy\n\nThe values quoted here are after subtracting the nearby extended emission\ncontribution from the SGR and doing the Tsys corection by a factor of\n3.875 at 240 MHz frequency. Tsys correction is required because of the\ndifferent sky temperatures off the galactic plane (position of SGR) and\noff the galactic plane (Flux calibrator).\n\nThe 608 flux density on Jan 10.16 UT and Jan 26.26 UT are 82.4 +/- 6.8 mJy\nand 19.3 +/- 5.9 mJy, after doing the Tsys correction by a factor of 1.87.",
