We report preliminary magnitudes for 2021 eruption of recurrent Nova M31N 2008-12a (ATEL #15034) observed under poor sky conditions, using the 0.7m robotic GROWTH-India telescope at the Indian Astronomical Observatory on 14 November 2021.
JD (Start) | Filter | Magnitude (AB)
2459533.231009 | g' | 18.28 +/- 0.13
2459533.234688 | r' | 18.35 +/- 0.12
2459533.238388 | i' | 18.59 +/- 0.20
The magnitudes are calibrated against PanSTARRS (Flewelling et al., 2018) and not corrected for Galactic extinction.
The GROWTH India Telescope (GIT) is a 70-cm telescope with a 0.7-degree field of view, set up by the Indian Institute of Astrophysics (IIA) and the Indian Institute of Technology Bombay (IITB) with funding from DST-SERB and IUSSTF. It is located at the Indian Astronomical Observatory (Hanle), operated by IIA. We acknowledge funding by the IITB alumni batch of 1994, which partially supports operations of the telescope.
