From the image below it is likely that star had returned to close to historic levels by T+5.7d and this indicates that the dimming was fairly quick. 2021-11-02 03:09:55 UT, mag 20.86 (T-12.0d) 2021-11-14 03:16:36 UT, mag 14.59 (T+0.00d) 2021-11-14 05:03:10 UT, mag 14.54 (T+0.07d) 2021-11-14 09:16:49 UT, mag 14.66 (T+0.25d) 2021-12-19 14:39:53 UT, mag 20.60 (T+35.5d) ] |
