  • Aurora unlikely. Tonight's forecast peaks at Kp 2.7. From here you'd usually need about Kp 9, which takes a rare, extreme storm.
  • Space station passes at 5:42, up to 13° high, moving S → E. It looks like a bright, steady star that crosses the sky in a few minutes.
  • Moon 42% lit (First Quarter), above the horizon for 30% of the dark hours.
  • Clouds: about 6% effective cover during dark hours, so mostly clear.
