Stanzin (IIA) report on behalf of the GROWTH collaboration:\n\nWe observed the field of GRB190530A reported by Fermi GBM Team (GCN 24676)\nat 2019-06-01.635 and 2019-06-02.685 UT with the 0.7m GROWTH-India\ntelescope. The images were taken in r filter. We detect a very faint source\nat position Ra: 08h 02m 07.73s, Dec: +35d 28m 47.7s. Photometric results\nobtained are as follow:-\n\n------------------------------------------------------------------\n\n MJD(Start)| Exposure(s) | Stacked   | Filter | Mag | Magerr |\n\n------------------------------------------------------------------\n\n58635.636 | 600  | No | r | 20.118 | 0.14 |\n\n58636.685  | 5*500 | YES | r | 20.48 | 0.11 |\n\n------------------------------------------------------------------\n\nMagnitudes are calibrated with panstarrs in the same field. Photometric\nresults are found to be in agreement with (Lipunov et al., GCN 24680; Kann\net al., GCN 24684; Heintz et al., GCN 24686; Izzo et al., GCN 24687; Xin et\nal., GCN 24688; Watson et al., GCN 24690; Lipunov et al., GCN 24693; Xin et\nal., GCN 24697; Belkin et al., GCN 24698; Kann et al., GCN 24700;Vinko et\nal., GCN 24709; Siegel, GCN 24703; Moskvitin and Uklein, GCN 24708; Belkin\net al., GCN 24712; Brajesh et al., GCN 24729). Using data of\nabove-mentioned GCNs along with GIT data, we found that source is fading\nwith a power law index of 1.52.\n\n\nThe fitted curve can be found here:\n\nhttps://lh5.googleusercontent.com/uyI9IhOx5bbe7_Ii-eHWsaj7r2Qw1g10_Lb_HIWKd5YBp8xsYC1OCPhdvYGifF80tkEgfWI-SMZl5RqgyRisuJS4mt3tHAIBEwoyVRJwX3B2LtsjVx1V=w572\n\nThe GROWTH India Telescope (GIT) is a 70-cm telescope with a 0.7 degree\nfield of view, set up by the Indian Institute of Astrophysics and the\nIndian Institute of Technology Bombay with support from the Indo-US Science\nand Technology Forum (IUSSTF) and the Science and Engineering Research\nBoard (SERB) of the Department of Science and Technology (DST), Government\nof India (https://sites.google.com/view/growthindia/).
