After 40 days with no sunspots on the Earth-facing side of the Sun, a new sunspot emerged near the southeast limb of the Sun on December 23, 2019, and was numbered Active Region 2753 on December 24. The region has magnetic polarity -/+, opposite of +/- magnetic...

Cosmic radiation has hit the 5-year high this month and is approaching record high values as the Sun sets a new Space Age record for spotlessness -- days without sunspots. The Sun’s magnetic field weakens during solar minimums, allowing deep space cosmic...

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 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...
October 25, 2019
A recurrent, positive polarity coronal hole high speed stream (CH HSS) is anticipated to rotate into an Earth-connected position on October 24. As a result, a G1 - Minor Geomagnetic Storm Watch is in effect for Thursday and Friday, October 24 and 25, 2019. A...

The solar wind environment is expected to become enhanced and disturbed later on September 27, 2019 (UTC). G1 - Minor Geomagnetic Storm Watch is in effect for September 27, G2 - Moderate for September 28. Quiet to unsettled geomagnetic field conditions are expected...

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...

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...
September 25, 2019
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...

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...

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...
May 14, 2019
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...

A moderately strong solar flare measuring C9.9 erupted from AR 2740 (Beta-Delta) at 05:10 UTC on May 6, 2019. The event started at 05:04 UTC and ended at 05:12 UTC. This is the strongest solar flare since M1.0 at 23:28 UTC on October 20, 2017. A Type II Radio...

An impulsive solar flare measuring C5.6 at its peak time erupted from AR 2736, the source of yesterday's C4.8 and associated asymmetric full-halo CME, at 03:12 UTC on March 21, 2019. The event started at 03:08 and ended at 03:15 UTC. There were no radio...
March 21, 2019
A solar flare measuring C4.8 at its peak erupted from newly-emerged AR 2736 on March 20, 2019. The eruption started at 10:35, peaked at 11:18 and ended at 11:34 UTC. The region was also responsible for several B-class flares over the past 7 hours. The flare was...
March 20, 2019
A long-duration solar flare measuring C1.3 at its peak erupted from Region 2734 (Alpha) at 03:19 UTC on March 8, 2019. The event started at 03:07, peaked at 03:19 and ended at 03:58 UTC. This event was associated with a Type II Radio Emission registered at 03:15 UTC...
March 08, 2019
An isolated, negative polarity Coronal Hole High Speed Stream (CH HSS) is affecting our planet on February 27 and 28, 2019, causing isolated periods of geomagnetic storming. Solar winds over the past 24 hours were indicative of an anticipated Solar Sector Boundary...
