9,572
Next 72hrs - QUIET. This weekend we are expecting overall QUIET conditions with some isolated minor STORM intervals due to a coronal hole. We anticipate the arrival of a coronal mass ejection by the end of the weekend causing some further minor STORM periods.
151
Next 24hrs - QUIET. We are anticipating elevated solar wind speeds due to a coronal hole, maybe leading to minor STORM periods of geomagnetic activity.
191
Next 24hrs - QUIET. Overall low geomagnetic activity is anticipated, with slight chances of ACTIVE/STORM periods if the coronal hole high-speed stream arrives earlier than expected.

210
Next 24hrs - QUIET. The CME from 6th June most likely missed the Earth but late arrival cannot be fully ruled out just yet. Chances of brief STORM intervals are still anticipated.

256
Next 24hrs -STORM. A CME that lifted off the Sun on 6 June is expected to arrive today. Geomagnetic activity may reach STORM G3 levels. ⚡️⚡️

248
Next 72hrs - ACTIVE- STORM. CME arrivals this morning have elevated solar winds with limited geomagnetic impacts due to positive Bz. Residual effects, coronal hole influence and a possible glance from another CME may enhance conditions later today.

272
Next 24hrs - STORM. Three CMEs erupted from the Sun yesterday with the first 2 likely to arrive later today. This will likely lead to significant geomagnetic activity to major STORM levels.

266
Next 24hrs - QUIET. Solar wind speeds are at near background levels and there are no Earth directed CMEs expected.

239
Next 24hrs - QUIET. Coronal hole influence is on a declining trend, however there still is a chance of some minor enhancements.

202
Next 72hrs - QUIET overall with some ACTIVE periods possible throughout the weekend due to ongoing Coronal Hole influence. Maybe a weak CME glance too but that is uncertain and in any event is unlikely to have any significant impact on geomagnetic activity.
2
197
Next 24hrs - QUIET overall although some ACTIVE periods are possible due to the influence of a Coronal Hole High Speed Stream.

200
Next 24hrs - QUIET overall with a chance of some occasional ACTIVE periods due to the influence of a Coronal Hole High Speed Stream.
1
219
Next 24hrs - QUIET initially today but influence from the High Speed Stream associated with a small Coronal Hole may increase tomorrow and could potentially bring some ACTIVE periods as the week progresses.
2
214
Next 24hrs - QUIET. Solar wind speed remains low, although it has increased slightly overnight but geomagnetic activity has remained muted, and QUIET conditions are expected to prevail over the next day or two.
2
262
Next 72hrs - QUIET. Solar wind remains at ambient levels, with no major enhancements expected over the weekend. Although chances of brief ACTIVE periods are possible due to the effects of a small coronal hole.

204
Next 24hrs - QUIET. Solar wind is back down near ambient conditions and no further disturbances are expected in the coming days. Geomagnetic activity is expected to stay largely QUIET in response.
2
248
Next 24hrs-QUIET. Solar wind parameters are continuing to head towards background levels. There's a very slight chance of a CME arrival today, which could lead to some ACTIVE or maybe brief STORM conditions, but geomagnetic conditions are expected to stay mostly QUIET.
3
235
Next 24hrs-QUIET. A CME arrived this morning and has already caused some ACTIVE conditions, and another CME may arrive later today. This is likely to mean we'll get some more ACTIVE conditions with a chance for some STORM periods.
1
201
Next 24hrs-QUIET. Effects of the high speed stream are waning so we're not expecting much geomagnetic activity - maybe a chance for some ACTIVE periods. There's a very slight chance of a glancing blow from a CME, which could briefly push activity up to STORM levels if it arrives
2
235
Next 72hrs - ACTIVE. We're anticipating the arrival of a high-speed solar wind stream in the next few hours. The fast solar wind is expected to influence the Earth's magnetic field though Friday and the weekend giving ACTIVE to STORM periods.
