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. 🔭
