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...

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...

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...

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...

Cosmic rays in Earth's atmosphere are intensifying for the 4th year in a row as the 11-year solar cycle plunges into one of the deepest minima of the Space Age. The finding comes from a campaign of almost weekly high-altitude balloon launches conducted by the...
February 27, 2019
A weak solar flare measuring C5.0 at its peak erupted from Active Region 2733 at 13:22 UTC on January 26, 2019. The eruption started at 13:12 and ended at 13:34 UTC. This was the strongest solar flare since February 18, 2018. It was preceded by B1.5 at 03:49 UTC,...

A positive polarity coronal hole high speed stream (CH HSS) is affecting our planet since late December 27, sparking G1 - Minor geomagnetic storm. Periods of active conditions are likely through December 29 followed by quiet to unsettled activity on December 30...
December 28, 2018
Our planet is under the influence of a positive polarity Coronal Hole High Speed Stream (CH HSS) over the past 24 hours. Geomagnetic storms reaching G2 - Moderate levels were registered November 5. Solar wind parameters reflected the passage of a Solar Sector...
