Solar activity
24 h Summary
Solar activity remained at low levels. The largest event of the period
was a C6.0 flare at 14/1113 UTC from Region 4374 (N10E02, Hsx/alpha).
New Regions 4376 (N13E54, Axx/alpha) and 4377 (N09E68, Cao/beta) were
numbered, though foreshortening affects complicates the classification
of the later. The remaining regions were stable or in decay. No
Earth-directed CMEs were detected in available imagery.
Forecast
Solar activity is expected to be at low levels, with a slight chance for
M-class (R1-R2/Minor-Moderate) flares through 17 Feb.
Energetic Particles
24 h Summary
The greater than 2 MeV electron flux reached moderate levels. The
greater than 10 MeV proton flux remained at background levels throughout
the period.
Forecast
The greater than 2 MeV electron flux is expected to reach moderate
levels on 15-16 Feb, before increasing to high levels on 17 Feb. The
greater than 10 MeV proton flux is expected to continue at background
levels through 17 Feb.
Solar Wind
24 h Summary
Solar wind parameters were consistent with waning negative polarity CH
HSS effects with potential embedded transients for most of the reporting
period, with the total magnetic field (Bt) averaging 7 nT, Bz
(north-south) component primarily northward averaging ~4 nT, with wind
speeds decreasing from ~500 km/s to ~350 km/s and a largely positive
(away from the Sun) Phi angle. Starting at ~14/1600 UTC, wind speeds
began to increase again, with the Phi angle switching into a largely
negative (towards the Sun) orientation. At 1835 UTC, Bt began to
increase, reaching a max of 15 nT at 1947 UTC, and Bz deflected strongly
southward and sustained that orientation through the end of the
reporting period, obtaining a max deflection of -14 nT at 1957 UTC. Wind
speeds peaked near 550 km/s at the end of the period.
Forecast
The solar wind environment is expected to remain enhanced through 17 Feb
due to CIR influences followed by the onset of positive polarity CH HSS
influences. Weak CME enhancements are possible on 15 Feb as a CME from
11 Feb passes in close proximity.
Geospace
24 h Summary
The geomagnetic field was quiet to active.
Forecast
Periods of G1 (Minor) storming are likely on 15-16 Feb, with a chance
for isolated G2 (Moderate) storming on 15 Feb, due to positive polarity
CH HSS influences. Weak CME enhancements are possible on 15 Feb as a CME
from 11 Feb passes in close proximity. 17 Feb is expected to reach
active levels.
