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...

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...

Earth is under the influence of a positive polarity coronal hole high speed stream (CH HSS) on October 7 and 8, 2018. G1 - Minor geomagnetic storm conditions were observed at 16:22 UTC and 20:42 UTC on October 7, 2018. A G2 warning has been issued and is valid until...
October 08, 2018
A G2 - Moderate geomagnetic storm watch has been issued for September 11, 2018 due to the onset of positive polarity coronal hole high speed stream. Solar wind parameters over the past 24 hours were descriptive of the passage of Co-rotating Interaction Region (CIR)...

Two plasma filament eruptions were detected on the Sun on July 5, 2018, and it seems at least one weak Earth-directed Coronal Mass Ejection (CME) was produced; ETA July 9 or 10. In addition, a relatively strong farside eruption took place on July 5 and its CME (not...
