ISS, Tiangong, Satellites Over Puna

[TomK]

Incidentally, if you want a challenge, but not one quite as difficult as spotting an Iridium satellite before it flares, the Hubble Space Telescope (HST) has some brightish passes over the island on the evenings of April 21, 22 and 23. It won't be anywhere near as bright as the ISS or the recent Iridium flares, but a nice opportunity to say you've seen one of the greatest scientific instruments of all time with the naked eye.

Please let me know if you're interested and I'll post details nearer the time.
