COMMENT: Solar activity was at very low levels. Spotless region NOAA 2696
(located at S12W55) was the source of a B9.5 flare peaking at 02:57UT,
during which its group filament was ejected. Coronal dimming and a coronal
wave were observed in SDO/AIA imagery. Preliminary analysis indicates that
the bulk of the associated coronal mass ejection (CME) is not earth-
directed. No earth-directed CMEs were observed in available coronagraphic
imagery. The greater than 10 MeV proton flux was at nominal levels.
Solar activity is expected to continue at very low levels.
Earth is under the influence of the high speed stream (HSS) from the trans-
equatorial extension of the negative southern polar coronal hole (CH).
Solar wind speed increased from an initial 460 km/s to its current 530
km/s, peaking around 00:40UT near 580 km/s (DSCOVR). Bz oscillated between
-6 and +8 nT. The interplanetary magnetic field was directed towards the
Sun.
The geomagnetic field was at quiet to unsettled levels, with an active
episode recorded at Dourbes during the 12-15UT interval. In response to
the
current HSS, mostly quiet to unsettled geomagnetic activity is expected
with a chance on an isolated active episode.
TODAY'S ESTIMATED ISN : 000, BASED ON 09 STATIONS.
