This rotation ran from 12/25/2015 1152 UT until 01/21/2016 1958 UT. During this time the Sun showed 16 Active regions (AR2470 to AR2487) of which the largest region became AR2173. This region grew to an Fkc on the McIntosh scale with 38 spots on 12/27, and the size of the region maxed out at 590 millionths on the same date. The region also produced the largest Flare, an M2.4, which maxed out at 00:10 UT on January 2nd. Here the image of AR2173 on December 27th by Rik Hill and an image submitted by Monty Leventhal of the M2.4 flare on 2016-01-02 ten minutes after the maximum.
