INCREASING CHANCE OF FLARES: NOAA forecasters have increased the odds of a flare today (40% M-class, 5% X-class) in response to developments inside sunspot AR3361. The active region has an increasingly unstable 'beta-gamma-delta' magnetic field that harbors energy for strong explosions. Any flares will be geoeffective as the sunspot is directly facing Earth.
