We report optical follow-up observations of the blazar BZQJ0348-2749 that showed a large NIR flare (Carrasco et al., ATel #12310), with the 0.7m robotic GROWTH-India telescope at the Indian Astronomical Observatory. The target was observed on UT 2018-12-21 at an airmass of 2.7 in r and i filters. Magnitudes were calculated using PanSTARRs reference stars in the same field. The measured magnitudes are:
?MJD ? ? Filter Magnitude
58473.752? i ? 16.07 +- 0.23
58473.778? r ? 16.37 +- 0.35
The object is considerably brighter than the quiescence values of r=19.50 +- 0.05 and i=18.88 +- 0.12 obtained from PanSTARRs.
GROWTH India telescope is a 70-cm telescope with a 0.7 degree field of view, set up by the Indian Institute of Astrophysics and the Indian Institute of Technology Bombay with support from the Indo-US Science and Technology Forum (IUSSTF) and the Science and Engineering Research Board (SERB) of the Department of Science and Technology (DST), Government of India (https://sites.google.com/view/growthindia/). It is located at the Indian Astronomical Observatory (Hanle), operated by the Indian Institute of Astrophysics (IIA).
