COMMENT: The only sunspot group currently reported on the solar disk,
Catania number 55, NOAA AR 2680, is unlikely to produce flaring activity
above the B-level. No flares were reported in the past 24 hours. The proton
event associated with the halo CME on September 10 is still ongoing.
A fast forward shock was detected in the solar wind by DSCOVR around 00:21
UT on September 14, with clear jumps of the solar wind speed, density,
temperature, and the interplanetary magnetic field (IMF) magnitude. The
solar origin of the shock is unclear. The solar wind speed in the post-
shock sheath region was around 390 km/s, so the departure from the Sun
on
September 10 in association with the limb full halo CME is possible. The
IMF magnitude in the sheath did not exceed 8 nT, with the north-south IMF
component fluctuating. Geomagnetic conditions remained quiet, with both
NOAA Kp and Dourbes K indices equalling 2.
The Earth is currently inside a slow (around 410 km/s) solar wind flow.
The
increase of plasma density and the IMF magnitude in the last couple of
hours may indicate the arrival of the interaction region between the slow
and fast solar wind flows. The fast flow emanates from a low-latitude
extension of the northern polar coronal hole, and its arrival can be
expected later today. Active to minor storm conditions may be expected.
TODAY'S ESTIMATED ISN : 012, BASED ON 19 STATIONS.
