  • Aurora unlikely. Tonight's forecast peaks at Kp 2.0. From here you'd usually need about Kp 9, which takes a rare, extreme storm.
  • Space station passes at 4:58, up to 22° high, moving W → N. It looks like a bright, steady star that crosses the sky in a few minutes.
  • Moon 38% lit (Waxing Crescent), above the horizon for 32% of the dark hours.
  • Clouds: about 5% effective cover during dark hours, so mostly clear.
