SOLAR WIND, INCOMING (UPDATED): A minor stream of solar wind is heading for Earth. ETA: March 31st. The gaseous material is flowing from a relatively small hole in the sun's atmosphere, now facing our planet. ( So visual aurora, if it happens may be earlier than already predicted)

X-CLASS SOLAR FLARE: This is becoming routine. The sun just produced another X-class solar flare, the 7th of 2023. The X1.2-category explosion came from sunspot AR3256 near the sun's South-western limb:

Radiation from the flare ionized the top of Earth's atmosphere, causing a strong shortwave radio blackout over southeast Asia, Australia and New Zealand. Ham radio operators may have noticed loss of signal below 30 MHz for as much as an hour after the peak of the flare (March 29th @ 02:33 UTC).


Luckily I wasn't awake at 0230! grin2

Nice that HF conditions are picking up anyway - good for QRP.
