Next 24 hours - QUIET. There may be a slight chance of some brief ACTIVE periods due to a mild enhancement in the solar wind, but QUIET conditions are expected to dominate.

Next 24hrs - QUIET. A high speed stream from a small coronal hole may lead to some ACTIVE intervals, but geomagnetic conditions are expected to remain largely QUIET.
0

Next 72hrs - QUIET overall but still a chance of an occasional ACTIVE period due to residual Coronal Hole influence, although this will decline as the weekend progresses. Possible glance from a weak CME on the 7th/8th could potentially push geomagnetic active to STORM G1 briefly.

Next 24hrs - ACTIVE. The expected coronal mass ejection (CME) arrived yesterday leading to ACTIVE & STORM periods. A combination of lingering CME effects and a high-speed stream from a coronal hole could result in further ACTIVE conditions.

Next 24hrs - STORM. A glancing blow from a coronal mass ejection (CME), associated with a X8.1 flare launched on the 1st Feb, is predicted to arrive in the next 24hrs. Geomagnetic activity could reach minor STORM levels following the CME arrival.

Next 24hrs - QUIET. Solar activity remains high with several M-class flares.

Next 24hrs - QUIET. Solar wind is at background levels and it was all QUIET geomagnetically over the weekend. The Sun however has been active with several M- and X-class flares over the past 24hrs. Further solar activity is likely.

Next 72hrs- QUIET. Coronal hole influence is on a declining trend and solar wind speeds are expected to return to background levels later in the weekend. Some small enhanced geomagnetic activity cannot be ruled out initially over the next day or two.

Next 24hrs-QUIET. Solar wind speeds are currently elevated due to continuing coronal hole influence. This could lead to some ACTIVE - STORM G1 geomagnetic conditions.

Next 24hrs-QUIET. The expected coronal hole high speed stream has arrived at Earth this morning. Solar wind speeds will continue to be elevated which may lead to some enhanced geomagnetic activity up to STORM G1.

Next 24hrs-QUIET. Solar wind parameters are just above ambient levels. A high speed stream is expected to arrive later from a trans equatorial coronal hole. This may lead to enhanced geomagnetic activity with some STORM G1 spells.

Next 24hrs-QUIET overall. Current coronal influence is waning but as minor effects persist there is an outside chance of isolated ACTIVE geomagnetic activity.

Next 72hrs-ACTIVE then QUIET. Spell of activity overnight was due to lingering CH-HSS effects. Further ACTIVE periods are still possible with a chance of a brief STORM G1. A CME seen on 22nd may glance us at the end of the weekend with brief STORM G1 possible again.

Next 24hrs-QUIET overall. The STORM is over and residual CME effects set to continue on a declining trend. Could still see a brief ACTIVE spell now and then. Early imagery of a filament eruption from a disk-centre location this morning shows a presence of a CME (more tomorrow).

Next 24hrs-STORM. The CME cloud continued to strongly influence Earth's magnetic environment and overall activity was at STORM G3 levels overnight. Further STORM periods are likely to occur but with a declining intensity. Two furthr M-flares this morning are under analyses.

Next 24hrs - STORM. The 18-JAN CME from X1.9 flare arrived last night at 19:17 UT. The BGS magnetometers recorded STORM G4 levels in response to the CME shock followed by STORM G3 levels overnight. The STORM is currently ongoing and expect similar levels of activity today.

It looks like a CME has just arrived, geomagnetic activity is ramping up in response so #aurora sightings are likely if you're under clear dark skies

Next 24hrs - STORM. A full-halo CME from an X1.9 flare followed by a filament eruption close to the source of the above flare likely to arrive later today resulting in significant geomagnetic activity of up to STORM G4 levels for the next couple of days.

Next 72hrs -QUIET. Solar wind speeds remain elevated today with a chance of isolated ACTIVE intervals. A coronal hole becomes geoeffective tomorrow, likely boosting speeds again and bringing possible STORM G1 intervals

Next 24hrs -QUIET. Solar wind speed is elevated, but the magnetic field orientation keeps things QUIET for now. No major geomagnetic activity expected today—enjoy the calm!
