COMMENT: Over the past 24 hours solar activity has been low. There have
been several B-flares flares originated at NOAA AR 2671 (McIntosh: Fai;
Mag.Type: Beta-Gamma) and at NOAA AR 2672 (McIntosh: Eai; Mag.Type: Beta-
Gamma). The biggest flare B5.4 peaked yestreday (26-Aug-2017) at 21:00
UT.
No Earth-directed CMEs have been detected over the past 24 hours. Solar
protons have remained at background levels. NOAA AR 2672 and one returning
active region are expected to produce more B-class flares over the next
24
hours. C class flares are also not excluded.
The solar wind speed has fluctuated around 360 km/s over the past 24 hours.
The total magnetic field strength has fluctuated around 6 nT. The Bz
component varied between -4.1 and 4.4 nT being mainly positive. Geomagnetic
conditions ranged between Kp index 1-3 (NOAA) and local K index 1-2
(Dourbes) over the past 24 hours. Geomagnetic conditions are expected to
be
quiet for the next two days. Quiet to unsettled conditions can be expected
on day three due to the weak influence of a negative polarity CH HSS.
TODAY'S ESTIMATED ISN : 033, BASED ON 22 STATIONS.
