As many UMSF members have likely noticed the current Solar Cycle (25) is off with a bang! https://en.wikipedia.org/wiki/Solar_cycle_2...progression.png. SOHO observations https://soho.nascom.nasa.gov/spaceweather/ coupled with daily comments in Space Weather https://spaceweather.com/ provide an excellent way to follow this activity.

Two items on the SpaceWeather page of (Oct 6 2023) https://spaceweather.com/archive.php?view=1...0&year=2023 are of interest concerning Solar Cycle 25. The magnetic poles of the Sun are rapidly disappearing based on measurements from the Solar Dynamic Observatory and may reverse before the year’s end. Magnetic flux from active regions of the Sun in 2022 and 2023 are weakening the Sun’s N and S polar field strength rapidly. Solar polar field reversals tend to occur at time of Solar Cycle maxima, suggesting an earlier than expected Cycle 25 peak.
Large farside sunspots continue to be observed by NASA's Mars Perseverance rover which images the sun daily to check the air for dust. https://spaceweather.com/images2023/06oct23/todaysimage.jpg shows the farside of the sunspots. |
