Truly remarkable at how long it lasted and the length of its course and brightness of its flashes. Bright enough to catch my eye from indoors through corner porch windows. Thrilling. Never seen anything like it. Somewhat similar to the russian video a few years ago but I opened the window to listen for a sound but didn't hear one (which I was a little glad of when I thought of the windows smashed in russia.

Remarks
It flashed/pulsed 2 - 3 times (irregularly) as it made a very, very long course across the sky. It took long enough time for me to call out several times to my daughter, stand up (I was inside a porch) and follow its path
