26 February


Following an active previous 24 hours, solar activity returned to low
levels during the period. Region 1990 (S13E57, Dkc/beta-delta), the
culprit for producing the X4/2n flare on Feb 25, was relatively quiet
this period, only producing an optical subflare. This region has
progressed farther onto the solar disk, allowing for better
identification of its magnetic configuration. It appears to have a
beta-delta configuration, which would explain the propensity for large
flare activity. Regions 1981 (S07W54, Eai/beta) and 1982 (S10W42,
Esc/beta-gamma) remained stable throughout the period, producing
isolated optical subflares with Region 1982 producing a C3/Sf flare at
26/0359 UTC. Region 1984 (S18W56, Cao/beta) exhibited growth in the
leader, intermediate, and trailer spots as well as slight growth in
overall areal coverage. This region produced two low-level C-class
flares. The largest flare of the period was a C5/1n at 25/1510
UTC, produced by Region 1986 (N14W12, Eao/beta-gamma), even though it
displayed signs of decay throughout the period. The other spot groups
were either stable or showing slight decay. Region 1991 (S25E57,
Dso/beta) was numbered during the period, but was quiet so far. There
were no Earth-directed CMEs detected during the period.
