A reminder…  If the sky is clear tonight, May 15, we can see a total lunar eclipse starting at 10:27PM, with full eclipse at 11:29PM. And before that, the International Space Station (ISS) will be visible for about 6 minutes starting at 9:55PM, appearing in the west, reaching a maximum elevation of 41 degrees, and disappearing in the northeast. The ISS circles the Earth every 90 minutes or so, but its visibility varies. You can check Spot the Station to find when and where it will be visible and sign up for alerts of when it’s most visible in your location.
