A significant CME blasted off the sun today, Oct. 22nd, around 1100 UT. Analysts at the Goddard Space Weather Lab say the cloud is heading for Mars, due to hit the Red Planet on Oct. 26th. (movie, forecast track)While looking at the latest STEREO Ahead images,
A Solar Flare reaching M1.6 peaked at 03:25 UTC Thursday morning and appears to be centered off the northwest limb near Sunspot 1318 which is rotating out of direct earth view.Solar activity remains at fairly low levels with only small to mid sized C-Class flares
An active region on the far side of the sun erupted on October 14 and hurled a significant coronal mass ejection toward Mercury and Venus. Analysts at the Goddard Space Flight Center expect the cloud to hit the innermost planet on October 15 around 08:30 UTC….
Minor geomagnetic storming (G1 on the Geomagnetic Storm Scale) is underway following the arrival at Earth of 1 or more Coronal Mass Ejections that erupted from the Sun late last week and into the weekend. Activity is not expected to strengthen much beyond current
A comet discovered by amateur astronomers on Friday, Sept. 30th, disintegrated in spectacular fashion the very next day when it plunged into the sun. The Solar and Heliospheric Observatory recorded the comet’s last hours. The end was punctuated by an unexpected
On October 1st around 10:17 UT, widely-spaced sunspots 1302 and 1305 erupted in quick succession, revealing a long-distance entanglement which was not obvious before. NASA’s Solar Dynamics Observatory (SDO) recorded the movie of the double blast:Since it was
Sunspot 1302 is back at it again, this time producing an X1.9 Solar Flare at 09:40 UTC. This major event resulted in an R3 level radio blackout as well as producing a 10.7cm Radio Burst (TenFlare). A fast moving type II sweep frequency event is reported also. As this
Earth-orbiting satellites have detected a long-duration X1.4-class solar fare coming from a new sunspot on the sun’s eastern limb. The blast, which peaked at 1100 UT, produced a significant CME, but the cloud is not Earth-directed.
On Sept. 19th, the STEREO-SOHO fleet of spacecraft surrounding the sun detected six coronal mass ejections (CMEs). Two of the clouds rapidly dissipated. The remaining four, however, are still intact and billowing through the inner solar system. Click to view a movie of
As predicted by analysts at the Goddard Space Weather Lab, a coronal mass ejection (CME) hit Earth's magnetic field at ~03:30 UT on Sept 17th. The impact sparked a moderate geomagnetic storm (in progress) and auroras around the Arctic Circle. High-latitude sky watch
