Fast wind storms and Europa plumes - Solar Storm Forecast by Dr. Tamitha Skov

A coronal hole that has brought us up to storm levels multiple times before is back and is sending us some fast solar wind yet again, Dr. Tamitha Skov said in her latest Solar Storm Forecast video. We have already bumped up to unsettled conditions and could hit...

Earth under the influence of positive polarity CH HSS, G2 - Moderate geomagnetic storm

Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS). This is causing G1 - Minor to G2 - Moderate geomagnetic storming. Solar wind parameters were at background levels until about 06:00 UTC on October 24 when co-rotating...

Century-class Solar Minimum in progress

The Sun was blank more than 89% of the time from June 22 - September 22, with only 6 brief and tiny sunspots and not a single significant solar flare during this period of extreme quiet, Dr. Tony Phillips of the SpaceWeather reports. "This is a sign that Solar...

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...

Earth enters a stream of fast-moving solar wind, G2 - Moderate Geomagnetic Storm Watch in effect

Our planet has entered a stream of fast-moving solar wind flowing from a large positive polarity coronal hole. A G1 - Minor Geomagnetic Storm Watch is in effect for August 31 and G2 - Moderate for September 1. Solar wind parameters reflected a slow regime through...

Irina Kitiashvili with the NASA Solar Cycle 25 Forecast

Next solar cycle - Solar Cycle 25 - is expected to be the lowest in 200 years. The forecast for the next solar cycle says it will be the weakest of the last 200 years. The maximum of this next cycle – measured in terms of sunspot number, a standard measure of...

5 Earth-directed CMEs, G3 - Strong geomagnetic storm

A several degree long solar filament south of the Region 2741 disappeared by approximately 15:14 UTC on May 13, 2019. Initial analysis suggests an Earth-directed component is likely with this Coronal Mass Ejection (CME). This is the fifth Earth-directed CME since...

Asymmetric full halo CME impact expected late May 11 into May 12

An asymmetric full halo CME with a likely Earth-directed component erupted May 6, 2019. The source is still unknown, it is possible this was another stealth CME. Sun's northeastern limb continued exhibiting increased CME activity on May 6 and 7, 2019. This...
