Optical B-band observed magnitude and the color index of RS Oph 2021 outburst from ANS (red circles) and TJO (green triangle) compared to that of 2006 eruption (black crosses, computed with respect to MJD of 53775.86, [70]). Top three panels show the color indices, while the bottom panel shows B magnitude evolution.
