Yesterday my area in Pennsy was treated to a mysterious sound coming from the sky just before 10:30. Thousands of people must have heard it. For about 7 minutes it sounded like a low note was being played on a pan flute. It didn't change intensity & there was no doppler effect. It seemed fixed & pervasive. It was LOUD.
I asked on FB if anyone else heard it & got a myriad of confirmations. I hope it's in the local paper today. There's so much incoming energy to our solar system something catastrophic may occur.
I recorded about 30 seconds of it to memorialize the sound. I wanted something to refer back to. Really cool for this Physics & Astronomy geek.
