Beautiful plasma eruption from flare M2.0-9.10.25

"Eruption occurred behind NW limb of☀️.Most likely culprit was AR13236, once again AR wake up at or behind the limbs.Due toCME occurring behind limb,an🌎directed component is highly unlikely"

Solar Flare Leaves Sun Quaking
📸 The first known sunquake, recorded by SOHO on July 9, 1996

Scientists have shown for the first time that solar flares produce seismic waves in the Sun's interior that closely resemble those created by earthquakes on our planet.

What is causing poor #AirQuality in #Milan ?😷

(1/2)🧵
Milan’s poor air quality stems from its spot in Italy’s Po Valley, wedged between the Alps & Apennines. The fertile plains host dense industry & farms, producing 35% of Italy’s crops plus bricks & tiles — but also major emissions.🚜🏭🔥 #MilanSmog

Two nights of 3:45am alarms, blazing full moon lighting the sky like daytime and washing out the light of everything else, comet included. Then two days of post-processing battles, as comet processing is maddeningly tricky.

But I finally pulled it off: here is C/2025 A6 Lemmon. 🔭
