We report radio observations of the V3890 Sgr obtained using the GMRT at 1.4 GHz and 610 MHz. The radio emission from the source was detected at 1.4 GHz with a strength of 17.0 (4.3) mJy on 2019 September 6.54 UT suggesting the presence of thermal emission. The thermal emission in X-ray around the same time was also reported by M. Orio et al. 2019 (#13083). From the radio detection reported by Nyamai et al. 2019 (#13089), it appears that the source is going through its rise phase at ~1 GHz.
No radio emission was detected at 610 MHz on 2019 Sept 07.67 UT with an upper limit of 0.2 mJy. Monitoring of the source with GMRT will be continued.
We thank the Centre Director, NCRA for allocating DDT time on GMRT and the staff of the GMRT who made these observations possible. The GMRT is operated by the National Centre for Radio Astrophysics of the Tata Institute of Fundamental Research (NCRA-TIFR).
