G1-G3 Watches for 17-19 August, 2022

Although geomagnetic storms are generally bad for HF propagation, there can be an enhancement at the beginning of a storm. That&#x27;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:&#x2F;&#x2F;www.ngdc.noaa.gov&#x2F;stp&#x2F;IONO&#x2F;rt-iono&#x2F;realtime&#x2F;BC840_foF2.png" rel="nofollow">https:&#x2F;&#x2F;www.ngdc.noaa.gov&#x2F;stp&#x2F;IONO&#x2F;rt-iono&#x2F;realtime&#x2F;BC840_fo...</a><p>At 22:05Z, the 3000km MUF (Maximum Usable Frequency) was 31.9 MHz.<p><a href="https:&#x2F;&#x2F;lgdc.uml.edu&#x2F;common&#x2F;ShowIonogramPage?mid=48624089&amp;ursiCode=BC840&amp;time=2022.08.17%2022:10:05.000" rel="nofollow">https:&#x2F;&#x2F;lgdc.uml.edu&#x2F;common&#x2F;ShowIonogramPage?mid=48624089&amp;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:&#x2F;&#x2F;lgdc.uml.edu&#x2F;common&#x2F;ShowIonogramPage?mid=48612891&amp;ursiCode=BC840&amp;time=2022.08.16%2022:10:05.000" rel="nofollow">https:&#x2F;&#x2F;lgdc.uml.edu&#x2F;common&#x2F;ShowIonogramPage?mid=48612891&amp;ur...</a>

There’s TamithaSkov space weather report on YouTube:<p><a href="https:&#x2F;&#x2F;youtu.be&#x2F;TCypTeodMYo" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;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:&#x2F;&#x2F;aurorawatch.lancs.ac.uk&#x2F;" rel="nofollow">https:&#x2F;&#x2F;aurorawatch.lancs.ac.uk&#x2F;</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&#x2F;astrophysics&#x2F;whatever scientist myself, but the page mentions &quot;the arrival at or near Earth of multiple coronal mass ejections (CMEs) that have departed the Sun since 14 Aug&quot;<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 &#x2F; (4 day * 24h&#x2F;day) ~= 1.5 million km&#x2F;h???

Would looking at the sun through a telescope (hobbyist level telescope with a solar filter) be especially interesting today compared to normal days?

Any particular effects on us here on Earth? Mainly auroras, I assume?

The forecast sounds like G3 will be hitting Europe, not the US.
