The first of several CMEs en route to Earth struck our planet’s magnetic field on Sept. 9th around 1130UT. The impact sparked a strong (Kp=7) geomagnetic storm, which is now subsiding. Last night Northern Lights were spotted in the United States as far south
UPDATE: The Geomagnetic Storm has subsided over the past few hours. However, the solar wind remains energized and occasional pulses of activity are expected for another 24 hours. Region 1283, the responsible party back at the Sun, decayed today. The Geomagnetic Storm
This morning at 0150 UT, sunspot 1283 produced an M5.3-class solar flare. A movie from NASA’s Solar Dynamics Observatory shows the flash of extreme UV radiation. Because of the sunspot’s central location on the solar disk, the eruption was Earth-directed and a CME
Yesterday, the Solar and Heliospheric Observatory witnessed a spectacular explosion on the sun that seemed to pass perilously close to Venus.As the movie shows, the CME passed harmlessly. There was no collision, and it wasn’t even close. Although Venus seems to be
This morning at 08:05 UTC, sunspot 1263 produced an X6.9 solar flare, the third X-flare of new Solar Cycle 24 and the most powerful so far. NASA's Solar Dynamics Observatory captured the explosion's extreme ultraviolet flash:The brunt of the ex
A second M-Class flare, this time a M2.5 took place at 03:54 UTC Tuesday morning around Sunspot 1263. This is in addition to the earlier M3.5 flare which we reported yesterday. The first flare produced a small, but fast moving (2010 km/s) Coronal Mass Ejection…
Earth's magnetic field is still reverberating from a CME strike on August 5th that sparked one of the strongest geomagnetic storms in years. Registering 8 on the 0 to 9 "K-index" scale of magnetic disturbances, the storm, at its maximum, sparked…
A geomagnetic storm is in progress. It began on August 5th around 18:00 UT when a CME struck Earth's magnetic field. At its peak during the hours just after impact, the storm registered 8 on the 0 to 9 "K-index" scale of geomagnetic disturbances,…
A major geomagnetic storm is in progress following the impact of a CME on August 5th around 1800 UT. Sky watchers at all latitudes should be alert for auroras after nightfall. Tip: the best hours for aurora sightings are usually around local midnight.Analysts at the
Sunspot 1261 is at it again, this time producing a strong M9.3 Solar Flare at 03:57 UTC Thursday morning. It also turns out that yet another Coronal Mass Ejection (CME) was produced and you can see it in the still image below captured by STEREO Ahead.Proton Levels are o
