A big detrimental polarity coronal gap is affecting our planet, inflicting G1 – Minor geomagnetic storming. Geomagnetic Okay-index of 5 (G1 – Minor geomagnetic storm) threshold was reached at 01:37 UTC, January 5, 2019.

Photo voltaic wind parameters, as measured by the DSCOVR spacecraft, indicated the onset of affect from a detrimental polarity CH HSS over the previous 24 hours. Whole magnetic subject power reached a quick peak of 14 nT round 17:00 UTC on January four. The Bz part reached as far south as -10 nT round 02:00 UTC, January 5. Photo voltaic wind speeds elevated from close to 350 km/s at 21:00 UTC, January four to peak of 558 km/s noticed at 10:12 UTC, January 5. Phi angle shifted from predominantly constructive to detrimental after 01:00 UTC, January  5.

Photo voltaic wind parameters are anticipated to proceed at enhanced ranges on account of CH HSS affect via January 6. Largely background circumstances are anticipated by the tip of January 7.

G1 -Minor geomagnetic storm circumstances are seemingly on January 5 as a result of continued affect of a detrimental polarity CH HSS. Unsettled to lively ranges are seemingly on January 6 and quiet to unsettled ranges are seemingly on January 7 as affect from the CH HSS slowly diminishes.

The larger than 2 MeV electron flux was at average to background ranges and the larger than 10 MeV proton flux was regular at background ranges over the previous 24 hours. The larger than 2 MeV electron flux is anticipated to be at regular to average ranges January 5, and average to excessive ranges January 6 and seven in response to a CH HSS. The larger than 10 MeV proton flux is anticipated to persist at background ranges via January 7.

Photo voltaic exercise remained very low over the previous 24 hours. Area 2732 (N09W68, Bxo/beta), the one numbered area, exhibited decay amongst all of the spots.

A Coronal Mass Ejection (CME) was noticed in LASCO C2 coronagraph imagery at 23:24 UTC on January 2, seemingly from a filament eruption that occurred close to (S71W49). Nonetheless, evaluation of STEREO and LASCO coronagraph imagery decided it to have a trajectory south and west of Earth. No impacts are anticipated from this occasion.
