This storm is amazing: it took only 38 hours (!), from Nov 2 ~05 UT to Nov 3 19:25 UT to travel all the 149.5 Mio km from☀️to 🌍. This is a mean speed of 1023 km/s or 3.7 Mio km/h or 2.3 Mio mph. The storm definitely got a tow by a slipstream from faster wind in front of it.

Quite unreal to announce that I got an @ERC_Research Consolidator grant for improving #spaceweather prediction! This is foremost a success by everyone in our team: Tanja/Ute Amerstorfer, Maike Bauer, Rachel Bailey, Martin Reiss, and Andreas Weiss. Best. team. ever. 🧵 1/18 👇

The 2021 October 28 #solarstorm in all its glory observed by SOHO. I see a clear asymmetry implying a tilted magnetic core, with an axis going from the bottom left to the upper right (or vice versa) - so if this flux rope impacts Earth, it has likely southward magnetic fields.

A first quick look at the @ESASolarOrbiter data from the magnetic field instrument @SolarOrbiterMAG at 0.83 AU and 19° away from the Earth quite clearly shows that there are 2 solar storms interacting (maybe merging?), different from the signatures we've seen so far at Earth.

The solar corona seen with the SOHO spacecraft is really exceptionally beautiful in the last few days, with the solar approach of #comet 96P/Machholz and a few minor #solarstorm eruptions. ☄️🌬️☀️

New magnetic field data from the @NASASun Parker Solar Probe spacecraft have been released today, giving us the very first ever data taken at a distance of < 0.1 AU or one tenth of the distance of the Earth from the Sun.

So far our prediction of this #solarstorm magnetic structure, based on☀️images as South-West-North (SWN), turned out correct. The magnetic field points south and west (SW), and this field should turn northward (N) soon, then #aurora is expected to (slowly) recede. 👇

Thus, the configuration on the Sun indicates a right-handed South-West-North (SWN) rotation of the flux rope. If correct, this means that the geomagnetic storm would start soon during Sunday night after a shock wave and the plasma pile up sheath region arrived.

With 2 or 3 #solarstorms incoming expected from Mon Aug 30 to Sep 2, the geomagnetic effects of this compound stream should last until Sep 4/5. Bad timing with Hurricane Ida, likely impacting radio comms for disaster response. This is a deja-vu of the Sep 2017 CMEs/Hurr. Irma.

Wow! The 2021 Oct 9 event could turn out to be a *very* interesting #solarstorm , for both research on the magnetic structure of CMEs and for its real time effects ( #aurora ) at Earth. @BepiColombo and @ESASolarOrbiter Orbiter are only 7 and 13 degree away from the Sun-Earth line.

Today's eruption/M1.6 flare from AR 12882 is not only thought to have launched an Earth-directed CME, but also was accompanied by an impressive large-scale EUV wave. It even spawned a secondary wave when it hit a region to southwest (lower right).

A new study by @swmcintosh et al. (under review) is a mind-blowing prediction for solar cycle 25 with a maximum sunspot number of 233 (which means flares, CMEs📈), doubling the amplitude of the last one. Compare to a mean cycle and the official forecast👇

The current equatorial coronal hole could lead to some high-speed stream driven #aurora activity at high latitudes from Mon Dec 27 to Thu Dec 30. 🇳🇴 🇮🇸 🇨🇦

Starting slowly tonight and peaking on Friday with 600 km/s a high-speed #solarwind stream will lead to some high-latitude #aurora intensification for the next few days. Happy #aurora hunting!

The 2nd expected #solarstorm impacted a few hours ago, with a really high speed of 800 km/s near Earth, presumably through a slipstream effect caused by the previous storm. For high-latitude countries in Europe this could be another great #aurora show tonight!

😮 @SolarOrbiterMAG has observed a #solarstorm on April 10 2023 right around its perihelion at 0.29 AU, peaking at 142.6 nT total field. A perfect observation of a left-handed magnetic flux rope, the field pointing to south (-Bz, blue), east (-By, green), and then north (+Bz).

The @NASASun Parker Solar Probe is right now making its 17th close approach to the Sun, all the way down to an incredible distance of only 0.053 AU from the Sun on Sep 27 23:30 UT. Besides setting new records more in situ data of the recent CME impacting Earth would be nice!

There is an ongoing arrival of a high speed #solarwind stream at Earth, similar to the previous solar rotation. Presumably its from a small coronal hole on the western ☀️hemisphere (on the middle-right in the image). Auroral energy input currently even 3x times above average.

In the wake of the current #solarstorm the Bz magnetic field at the Sun-Earth L1 point has dipped < 0 for a few hours now, and we are at the brink of another moderate geomagnetic storm. However, at STEREO-A which gives us a glimpse ~3 hours into the future Bz >0 again.

After the shock of the Nov 2 #solarstorm impacted on Nov 3 19:25 UT, it does look like we are going into the magnetic core of the storm. It has southward pointing fields (yay!), driven with 700 km/s towards the magnetosphere, thus pushing the energy input to 7 times above normal.
