Bright airglow at La Silla

Bright airglow at La Silla

The night after our observations, we spent one more night at La Silla before our transport back to La Serena. We were out taking photographs when the airglow became very strong, just about visible to the naked eye and very bright on a long exposure photograph. An observer from the Swiss Telescope came out to check out the skies as well.
