The variation in the solar wind velocity (V), density (N), dynamic pressure, the subsolar distance of modeled magnetopause, SYM-H and ASYM-H during magnetic storm on March 26, 2025. Red shaded regions represent the time periods when red auroras were observed by citizen scientists in Japan. Blue shaded regions show the time period of the subsolar distance of modeled magnetopause become smaller than 6.6 RE. Green shaded regions denote the time period of the GMC event observed by GOES 16 satellite. Red bar describes the time interval of calculated median value of V, N and Pd described in Table 1.
