Query: Photometry and preliminary modelling of Type IIb Supernova 2017gpn   MASTER OT J033744.97+723159.0/SN 2017gpn was discovered in the error-box of
LIGO/Virgo G299232 gravitational wave alert. The spectrum of SN 2017gpn is
consistent with a Type IIb supernova. In this work we present the photometry of
20 epochs of observations performed with CCD-photometer on the Zeiss-1000
telescope. The light curves in B and Rc filters were obtained. The multicolour
light curves were also modelled numerically using the one-dimensional radiation
hydro-dynamical code STELLA.
