P. Chandra, Tata Institute of Fundamental Research, Mumbai, reports the low-frequency radio detection of the soft gamma-ray repeater SGR 1806-20 (cf. IAUC 5875) with the Giant Metrewave Radio Telescope on Jan. 4.409 UT. The flux density at 608 MHz was 198.9 ± 11.9 mJy, while at 240 MHz it was 242.6 ± 14.9 mJy. The power-law index between the two frequencies is -0.21 ± 0.09, which is substantially flatter than that reported for the higher- frequency VLA observation on Jan. 4.59 by Cameron and Kulkarni (GCN 2934; alpha = -0.74 at 1.4 GHz) or -0.61 ± 0.06 reported by Gaensler et al. at the same time and frequency (GCN 2933).
