my app alerts for ISS Detector and Iridium 57

One of the sparkly bits of joy in my life is the app on my Kindle Fire HD8 that gives me a five-minute alert whenever either space vehicle (ISS or Iridium) is going to pass overhead, meaning literally to pass over the sky above me.  This is an ever renewing thrill for me.

ISS = International Space Station

Iridium 57 = “The Iridium satellite constellation provides L-band voice and data coverage

to satellite phones, pagers and integrated transceivers over the entire Earth surface.”
