Bulletin

Beta region NOAA AR 2712 developed several small spots between the leader and follower spots and produced two B1.1 flares. The chance for a C flare in the next 24 hours is estimated at 25%.

No Earth-directed Coronal Mass Ejections (CMEs) were observed in available coronagraphic imagery.

The greater than 10 MeV proton flux was at nominal levels in the past 24 hours, and is expected to stay at nominal levels in the next 24 hours.

Solar wind speed near Earth as registered by DSCOVR increased from about 340 to about 410 km/s in the past 24 hours. The Interplanetary Magnetic Field (IMF) was directed away from the Sun and its magnitude varied between about 2 and 7 nT. Bz was never below -5 nT. On May 28, the solar wind near Earth may experience the weak influence of a solar wind stream from a low latitude extension of the positive polarity north polar coronal hole.

Quiet geomagnetic conditions (K Dourbes between 1 and 2; NOAA Kp = 1) were registered in the past 24 hours. Quiet to unsettled levels (K Dourbes < 4) are expected on March 28, 29 and 30, with a chance for active intervals (K Dourbes = 4) due to the weak influence of an expected solar wind stream from a low latitude extension of the positive polarity north polar coronal hole.
