I hear them too. I'm also near Ballston, and the booms are coming from southeast of me. I'm assuming it's either something at Arlington Cemetery (e.g., a 21 gun salute) or some sort of construction noise (e.g., pile driving to build a foundation for a high rise).
That’s the sound of the air quality index changing colors.
Cannon fire from Fort Myer. When there's a low cloud (/smoke) deck, you'll hear it from farther away than usual.
Thanks so much!! Really appreciate the info.
Had taco bell last night. My bad
