Although geomagnetic storms are generally bad for HF propagation, there can be an enhancement at the beginning of a storm. That's what happened today and can be seen in this plot of the Boulder foF2 (the maximum frequency returned from directly overhead).<p><a href="https://www.ngdc.noaa.gov/stp/IONO/rt-iono/realtime/BC840_foF2.png" rel="nofollow">https://www.ngdc.noaa.gov/stp/IONO/rt-iono/realtime/BC840_fo...</a><p>At 22:05Z, the 3000km MUF (Maximum Usable Frequency) was 31.9 MHz.<p><a href="https://lgdc.uml.edu/common/ShowIonogramPage?mid=48624089&ursiCode=BC840&time=2022.08.17%2022:10:05.000" rel="nofollow">https://lgdc.uml.edu/common/ShowIonogramPage?mid=48624089&ur...</a><p>Comparing with the previous day, you can see that the ionosphere is much stronger (at least over Boulder) today.<p><a href="https://lgdc.uml.edu/common/ShowIonogramPage?mid=48612891&ursiCode=BC840&time=2022.08.16%2022:10:05.000" rel="nofollow">https://lgdc.uml.edu/common/ShowIonogramPage?mid=48612891&ur...</a>
There’s TamithaSkov space weather report on YouTube:<p><a href="https://youtu.be/TCypTeodMYo" rel="nofollow">https://youtu.be/TCypTeodMYo</a><p>And there’s Lancaster University’s Aurora Watch, I’ve been brushing off the alerts since there’s so many low level ones. I’ll need to up the threshold.<p><a href="https://aurorawatch.lancs.ac.uk/" rel="nofollow">https://aurorawatch.lancs.ac.uk/</a><p>But yeah, I might get to see what my degree project was about.<p>[Hopefully without getting Carringtoned, assuming this storm goes to about 5 - 10% of the magnetic field of the estimated Carrington Event and if such a comparison is linear]
Not a planetary/astrophysics/whatever scientist myself, but the page mentions "the arrival at or near Earth of multiple coronal mass ejections (CMEs) that have departed the Sun since 14 Aug"<p>Assuming the CMEs arrive around 18 Aug, and that the distance between the Sun and the Earth is ~150 million km, does that mean CMEs travel at around ~ 150 million km / (4 day * 24h/day) ~= 1.5 million km/h???
