Deep-space radiation reaching a percentage point of Space Age maximum

Solar activity is at very low levels and the visible disk remains spotless for the 17th day in a row, making a total of 33 days in 2020 or 66 percent -- we are still in a Solar Minimum, which is expected to end sometime this year. As a result of weakened Sun's...

Unsettled geomagnetic field due to CH HSS influences

Solar wind parameters in 24 hours ending 12:30 UTC today were indicative of a slightly enhanced and disturbed interplanetary magnetic field (IMF) due to weak coronal hole high speed stream (CH HSS) influences. Total IMF strength was variable, but steadily increased...

First multi-spot group of Solar Cycle 25 - Active Region 2753 numbered on December 24, 2019

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 around us reaching record high levels as the Sun sets Space Age record for most days without spots

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...

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...

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...
