An interplanetary shock wave from yesterday's CME hit Earth's geomagnetic field at 20:23 UTC today. At the time, Boulder station measured magnetic field Bz component deviation of 62 nT. A G1 (minor) geomagnetic storm is currently underway. High
A large prominence located off the northeast limb erupted early on Tuesday, October 8, 2013. A non-Earth directed Coronal Mass Ejection (CME) was associated with the event.There are currently 6 numbered sunspot regions on the disk.1855 – Beta1856 – Beta1857 – Alpha1860
A long duration C1 solar flare erupted on October 6, 2013 at 14:24 UTC. Coronal Mass Ejection associated with this event is Earth directed. Plasma cloud is forecast to sweep past our planet sometime on October 9 resulting in minor increase in geomagnetic
A G2 geomagnetic storm is now in progress following CME impact on Earth's magnetic field early on October 2, 2013. The ACE spacecraft detected a solar wind increase to above 600 km/s and the Bz component (IMF) initially tipped sharply south to -19nT.
A large magnetic filament erupted on Sun's northern hemisphere during the late hours (UTC) of September 29, 2013. The explosion hurled a magnificent Coronal Mass Ejection (CME) into space and it does look like it has an Earth-directed component.
There is still only a handful of spacecraft to watch for solar and magnetic storms but the number of observatories has been growing over the last six years. Today, these spacecraft have begun to provide the first multipoint measurements to better understand space
A long duration C-Class solar flare reaching C8.3 erupted on August 30, 2013 peaking at 02:46 UTC. The event started at 02:04 UTC and ended at 04:06 UTC. Associated was Type II and Type IV radio emissions. Type IV emissions occur in association with major
An icy comet with estimated size of few tens of meters plunged into the Sun on August 19/20, 2013 but just before it dissipated, a far-side region on the Sun expelled a magnificent full-halo CME.
Today's comet belonged to Kreutz Sungrazer family which
A large solar filament located in the southern hemisphere lifted off the Sun at about 8:50 UTC on August 20, 2013. A bright Coronal Mass Ejection (CME) was produced as the result. Though the majority of Sun's material is directed south current
An impulsive solar flare reaching M3.3 erupted on August 17, 2013. The event peaked at 18:24 UTC from Active Region 1818. AR 1818 is classified with Beta-Gamma-Delta magnetic configuration and is capable of producing even stronger eruptions.
