Spot temperature range estimates.

13-14-15/12/2021	B − R − V	$3846_{- 440}^{+ 270}$ $3846^{+270}_{-440}$

Notes. Spot temperature range estimates for each independent set of observations in the hypothesis of one spot. For the set marked with “*” we used only V and R data because B data had a low S/N, while for the same reason we used V, R, and I data for the last set (marked with “**”).
