Glancing-blow expected after weak B1.2 solar flare

A weak solar flare measuring B1.2 at its peak erupted on August 16, 2020, producing a coronal mass ejection (CME). Consensus model results suggest an arriving glancing blow on August 20 -- producing unsettled to active geomagnetic field conditions, with a chance for...

Solar storm hits Earth, sparking active geomagnetic conditions

Our Sun launched two solar storms this week, one of which was Earth-directed, Space Weather Physicist Dr. Tamitha Skov reports in her latest space weather forecast released July 14, 2020. The storm has hit, right on time, and all through the night people have been...

Enhanced solar wind environment after glancing blow from a slow-moving CME

Solar wind parameters over the past 24 hours were indicative of enhanced solar wind environment, likely caused by a combination of a glancing blow from a slow-moving Coronal Mass Ejection and influences of a negative polarity CH HSS. Total IMF strength was at 5 to 6...

CME hits Earth, sparks G2 - Moderate geomagnetic storm

A coronal mass ejection (CME) produced by the July 14th M2.4 long-duration solar flare hit Earth's magnetic field at 06:01 UTC on July 16, 2017. G2 - Moderate geomagnetic storming started 9 hours later. The S1 Minor solar radiation storm that started at 09:00...

Partial-halo CME impact sparks G1 geomagnetic storm

A partial-halo coronal mass ejection (CME) produced on June 28, 2017 hit Earth's magnetic field at 17:12 UTC on July 1, almost 24 hours earlier than expected. The impact was weak but managed to spark a G1 - Minor geomagnetic storm 17 hours later. G1 Watch...

Two CMEs heading toward Earth, severe geomagnetic storms expected

There are currently two Coronal Mass Ejections (CMEs) heading toward our planet and their combined arrival is expected to spark severe geomagnetic storms.The first one, released by the long duration M4.5 solar flare on September 9, is expected to hit Earth's magneti
