Latest Space Weather News Incoming CME Detected June 30, 2026 @ 11:50 UTC (UPDATED) The edge of a slow moving CME observed leaving the Sun on June 26th has finally been detected. A passage past our planet should be expected within the next hour or so. The solar wind speed only increased to around 440 km/s, although there was a noticeable increase in plasma density and strength (Bt). More to follow whenever necessary. UPDATE: Magnetometers are showing an impact to Earth's geomagnetic field at 11:53 UTC (June 30). Although not a strong impact, we will wait to see what happens, especially with the Bz component of the interplanetary magnetic field (IMF). Space Weather Update June 29, 2026 @ 12:40 UTC Below is an updated look at the two big sunspot regions facing Earth on Monday. Of the two, AR 4479 appears to be more magnetically complex and has been the main source of minor C-Flares so far today. There will remain a chance for a moderate M-Flare during the next 24 hours. Speaking of M-Flares, the ESA solar orbiter did detect an M4 flare off the farside of the Sun today and the source may have been another large sunspot forming that is visible in their latest imagery. A minor (G1) geomagnetic storm watch is now in effect for the next 24 hours due to the expected arrival of a slow moving CME that left the Sun on June 26th. More updates will be provided whenever necessary. CME Alert June 27, 2026 @ 03:10 UTC (UPDATED) This event is a little sneaky, however a slow moving coronal mass ejection (CME) was observed leaving the Sun following an event beginning around 20:15 UTC (June 26). At first it would seem that the eruption originated from either the farside of the Sun or the southern pole region, however STEREO-Ahead imagery shows it to be more of an Earth facing event. Coronal dimming is evident using the Solar Demon website in the vicinity of AR 4475 in the southern hemisphere. While the majority of plasma is heading south of the Sun-Earth line, the northern edge may be Earth directed. If so, a passage may be possible within 72-96 hours due to the slow moving nature of this event. More details to follow whenever necessary. UPDATE: As per the latest NOAA/SWPC update, the slow moving CME is expected to pass mostly south of the Sun-Earth line with a glancing blow possible by June 30th. More updates in the days ahead whenever necessary. Space Weather Update June 26, 2026 @ 12:55 UTC Below is an updated look at AR 4478 on Friday as seen by SDO/HMI. The sunspot cluster only manged low to mid level C-Flares so far today, but will remain an ongoing threat for an M-Class solar flare (50%). Elsewhere, AR 4475 located near center disk chipped in with a few minor C-Flares as well. Overall, there is about a 10% chance for a strong X-Class flare according to the latest NOAA/SWPC update.
