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.

The ionosphere is certainly starting to show a strong response to the new cycle - see https://spawx.nwra.com/spawx/ssne-year.html.

These are good suggested websites; I would add to them:

The MAVEN presentation at the MEPAG addressed how it is measuring atmospheric escape at Mars as the solar cycle ramps up. It says it may be constraining this better for Mars than for Earth.
https://mepag.jpl.nasa.gov/meeting/2022-01/...ven_2022_01.pdf In other news, SpaceX/Starlink lost 40 satellites between Feb 3 and Feb 8 before they could move out of their deployment orbit... because a solar event puffed up the atmosphere. Crazy. |

As Solar Cycle 25 activities increase, CME’s directed at Earth are more likely. In fact, the site of a large solar CME on Feb 17th https://spaceweatherarchive.com/2022/02/19/...ide-of-the-sun/ is expected to rotate into view over next few days. This area may be sunspot AR2936 who’s activity likely was responsible for the Starlink satellite incident https://spaceweatherarchive.com/2022/02/09/...rlink-incident/ mentioned by stevesliva in the previous post. It would be interesting if one could monitor proton flux data (see Juramike’s awesome method described here http://www.unmannedspaceflight.com/index.php?showtopic=6715) using upcoming SOHO movie images of the sun.

It would be interesting if one could monitor proton flux data Isn't there some L1 proton flux data available from ACE or DSCOVR? See, for example this SWPC page. |

As fredk mentions above there are other satellites orbiting the sun at Lagrange 1 point (L1) including the Advanced Composition Explorer (ACE) satellite https://www.swpc.noaa.gov/products/ace-real-time-solar-wind and the DSCOVR (Deep Space Climate Observatory) https://www.ngdc.noaa.gov/dscovr/portal/#/ satellite besides SOHO (Solar and Heliospheric Observatory) https://space.umd.edu/pm/ that monitor energetic properties of the solar wind in near real time and provide data portals that plot proton flux density and solar wind velocity. These are great resources to follow the sun’s activity.
Juramike’s method http://www.unmannedspaceflight.com/index.php?showtopic=6715) is certainly more hands on and fun and comparisons with the spacecraft data might be illuminating and satisfying! |

Some interesting predictions and possible mechanisms concerning the strength of Solar Cycle 25 are highlighted in Spaceweather https://spaceweatherarchive.com/2022/02/25/...nt-has-arrived/ today. A link to a paper published in 2020 concerning the effect of overlapping solar magnetic activity cycles and sunspot number is here: https://link.springer.com/article/10.1007/s...07-020-01723-y/

Additional information that Solar Cycle 25 is intensifying is provided by data from NASA’s TIMED spacecraft https://www.nasa.gov/centers/goddard/pdf/11...-GSFC-TIMED.pdf and summarized in some detail here https://spaceweather.com/ .

This is ångström 171, 193 & 211 data from Solar Dynamics Observatory, on March 23rd & 24th, 2022.
14,522 frames were repaired, graded, blended & rescaled to create the footage. Here it is on Youtube Samples... -------------------- |

The Space Weather Prediction Center in conjunction with NOAA has an informative interactive data plot of Solar Cycle 25's observed increased activity versus the predicted official forecast https://www.swpc.noaa.gov/products/solar-cycle-progression.

Most recent summary (April data) from https://www.swpc.noaa.gov/products/solar-cycle-progression and recent CMEs https://spaceweather.com/ (fortunately not headed at Earth) remind us (as did Mongo’s posts here in 2014 http://www.unmannedspaceflight.com/index.php?showtopic=7843 and this link https://science.nasa.gov/science-news/scien...jul_superstorm/ of consequences related to our Sun’s increasing activity. While Earth has multiple sun-montoring satellites to tell us of oncoming solar storm events we mainly have Earth’s magnetic fields to mitigate the effects of those storms.
