Solar activity was low. A C3/1n flare was observed from Region 1444 (N19E11) at 25/0028Z. This was followed by dimming in SDO/AIA 193 imagery north of Region 1444 at 25/0034Z. At 25/0448Z, a CME was observed in SOHO/LASCO C2 coronagraph imagery emerging from the northeast limb . A C2 flare occurred at 25/0157Z from Region 1445 (S24E52). Material was seen lifting off the southeast limb near Region 1445 at 25/0138Z in SDO/AIA 304 imagery. At 25/0512Z, a CME was observed in SOHO/LASCO C2 coronagraph imagery emerging from the southeast limb. Neither CME is expected to be particularly geoeffective. Region 1445 grew substantially over the past 24 hours and was classified as an Fho type group with beta magnetic characteristics. New Region 1446 (N23W27) was numbered today and classified as a small Bxo type group with beta magnetic characteristics.

Solar activity is expected to be low with a chance for an M-class flare. Old Region 1429 (N19, L=295) is expected to return late on Day 3 (28 March), further increasing the possibility of an M-class event.

The geomagnetic field was quiet. Solar wind speed, measured at the ACE spacecraft, decreased over the past 24 hours and ended the period around 370 km/s. Bz was generally neutral.

The geomagnetic field is expected to be quiet for Days 1 and 2 (26-27 March), increasing to unsettled to active conditions on Day 3 (28 March) as a recurrent coronal hole high speed stream becomes geoeffective.
