Solar Storm Hits Earth’s Magnetic Field

March 17, 2015By
A G4 (Severe) geomagnetic storm was observed today at 07/1358 UTC (09:58 am EDT). This is the response to a pair of CMEs observed leaving the Sun on 15 March. Shown here is a model depiction of where the aurora is likely visible. Storm conditions are forecast to persist for the next several hours before beginning to wane down towards the end of the UT day.

A G4 (severe) geomagnetic storm is now taking place, the most powerful solar storm of the current solar cycle, reports Discovery.com. Initially triggered by the impact of a coronal mass ejection (CME) hitting our planet’s magnetosphere, a relatively mild geomagnetic storm erupted at around 04:30 UT (12:30 a.m. EDT), but it has since become a severe G4-class geomagnetic storm. Bright auroras were sighted... read more

Soyuz’ Block I third stage is mated to the launcher at the Spaceport’s MIK integration building.

Preparations for Arianespace’s next Soyuz flight, which will lift into orbit two more Galileo satellites, are in full swing at multiple locations across the spaceport in French Guiana. Work includes a key integration step for the medium-lift launcher, plus the start-up of fueling for its Galileo satellite passengers. Soyuz’ Block I third stage was mated to the vehicle’s core during activity today in the... read more
