Highlights of Solar and Geomagnetic Activity
07 - 13 January 2019
Solar activity was very low. The solar disk was spotless during the
reporting period. No Earth-directed CMEs were observed.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit reached
high levels on 07-10 Jan and moderate levels on 11-13 Jan. The peak
flux was 2,970 pfu observed at 07/2040 UTC.
Geomagnetic field activity ranged from quiet to active levels. Solar
wind parameters began the period under waning negative polarity
coronal hole high speed stream (CH HSS) effects. Solar wind speed
began the period near 535 km/s, but diminished to near 345 km/s by
10/0720 UTC. Total field remained at 6 nT or less during this time.
The geomagnetic field responded with quiet to unsettled levels on 07
Jan followed by quiet levels on 08-10 Jan. By late on 10 Jan, solar
wind speed once again increased to near 515 km/s by 11/0435 UTC
while total field only increased briefly to a maximum of 8 nT at
11/0635 UTC. The Bz component deflected southward for approximately
3 hours to near -6 nT. The geomagnetic field responded with an
isolated active period on 11 Jan. By 12 and 13 Jan, solar wind speed
had decreased to below 400 km/s. The geomagnetic field was once
again quiet on 12-13 Jan.
Forecast of Solar and Geomagnetic Activity
14 January - 09 February 2019
Solar activity is expected to be at very low levels on 14-19 Jan and
03-09 Feb. A slight chance for C-class flares is expected on 20
Jan-02 Feb due to the return of old Region 2732 (N09, L=215).
No proton events are expected at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit is
expected to reach high levels on 25-27 Jan and 02-06 Feb due to
recurrent CH HSS influence.
Geomagnetic field activity is expected to be at unsettled levels on
15-16 Jan. Unsettled to active levels are expected on 24-26 Jan and
31 Jan - 03 Feb with G1 (Minor) storm levels likely on 24 Jan due to
recurrent CH HSS effects.
