Long Jupiter -148 area 200
New region 12824 [N19E66] rotated into view on May 17 and was numbered the next day by SWPC. The region was mostly quiet and in slow decay. A C1.1 flare was recorded at 02:09 UT.report(past month only)

N20E27 Data 2021-05-21
Long Jupiter -106 area 230
Region 12824 [N20E27] became unstable and developed polarity intermixing to the south and east of the largest spot. Several C flares have been recorded on May 22 and there is a chance of M class flaring.report(past month only)

N20E13 Data 2021-05-22
Long Jupiter -91 area 250
Region 12824 [N20E13] produced 2 minor M class flares and 9 C class flares as two weak magnetic deltas formed to the west and south of the major spot. The western delta is small and close to the largest spot while the southern delta is more interesting as a channel of positive polarity is wedged between two areas of negative polarity. The most interesting event of the day was a C1.3 long duration event which peaked at 08:44 UT and was associated with a faint halo CME.report(past month only)

N19W00 Data 2021-05-23
Long Jupiter -79 area 240
Region 12824 [N19W00] simplified magnetically as the small deltas from the previous day disappeared. Only minor polarity intermixing was observed by the end of the day. C are still likely, but less frequent than over the last couple of days. There is a chance of minor M class flaring as well. The main penumbra became symmetrical and lost area.report(past month only)

N19W52 Data 2021-05-27

N19W66 Data 2021-05-28
Long Jupiter -7 area 250
Region 12824 [N19W66] changed significantly as the two largest penumbrae merged and formed a magnetic delta. A C9.4 long duration proton flare peaked at 23:13 UT. Strong coronal dimming was observed far from the eruption site and well into the eastern hemisphere. There s a 6-hour data gap in LASCO imagery after this event, and it is uncertain if the associated CME had any Earth directed component.report(past month only)
