Here's a variety of #SpaceAudio #Whistlers for the aficionados out there, recorded by Van Allen Probes B Waves instruments #OTD 10 years ago.

Sticking with my 10-years-ago #OTD #SpaceAudio theme, even though (suprisingly) there were no "pew pew pew" whistlers recorded by the Van Allen Probes instruments, here's a nice quiet walk on Dagobah. Swamp noises are #chorus with just a couple far away blaster shots (#whistlers) near the end. #MayThe4thBeWithYou
