Here is this week's space weather and geophysical report, issued 2023 Feb 20 0155 UTC.
Highlights of Solar and Geomagnetic Activity 13 - 19 February 2023
Solar activity was at low to high levels during the period. M-class (R1-Minor) activity was predominate during 13-16 Feb with weak M-class flares observed from Regions 3213 (N30, L=223, class/area Fki/480 on 12 Feb), 3226 (N11, L=113, class/area Dki/480 on 14 Feb) and 3229 (N25, L=035, class/area Dko/400 on 17 Feb). The largest of these events was a long duration M2.6 from Region 3213 at 14/1212 UTC. This region also produced an M1.0 at 15/2114 UTC wth an associated Type II radio Sweep (576 km/s) and a projected glancing blow CME.
X flare activity was present on 17 Feb when Region 3229 produced a long duration X2.2/2b (R3-Strong) event at 17/2016 UTC. Associated with this flare was a fast Type II Sweep (1250 km/s) and an associated assumetric, halo CME. 18-19 Feb witnessed C-class activity during those two days.
No proton events were observed at geosynchronous orbit.
The greater than 2 MeV electron flux at geosynchronous orbit was at high levels on 13-14 Feb with a maximum flux of 5,450 pfu observed at 13/1725 UTC. Normal to moderate levels were present on 15-19 Feb.
Geomagnetic field activity generally ranged from quiet to active levels with some isolated minor storm periods (G1-Minor). Quiet conditions persisted through 13 Feb. quiet to unsettled levels were observed on 14 Feb, increasing to unsettled to G1-Minor levels on 15-16 Feb, all due to CME effects. Quiet to unsettled levels were present on 17 Feb due to weak positive polarity CH HSS effects. Mostly quiet levels persisted on 18-19 Feb.
Forecast of Solar and Geomagnetic Activity 20 February - 18 March 2023
Solar activity is expected to be at low to M-class flare activity (R1-R2, Minor-Moderate) levels throughout the outlook period.
No proton events are expected at geosynchronous orbit. However, a chance for a proton event exists throughout the period from the more complex, magnetically active regions.
The greater than 2 MeV electron flux at geosynchronous orbit is expected to be at high levels on 07-13 Mar. Normal to moderate levels are expected on 20 Feb-06 Mar and 14-18 Mar.
Geomagnetic field activity is expected to range from quiet to minor storm levels (G1-Minor). Active to G1-Minor levels are expected on 20-21 Feb due to CME effects. Unsettled to active conditions are expected on 22-24 and 27-28 Feb, 02, 05-08 and 15-17 Mar due to CH HSS effects.
