Purple Sky Promises Good Observations

Just after sunset, the thin purple clouds cover the ALMA Array Operations Site (at an altitude of 5,000 meters). Just above the ALMA antennas, the reclining Southern Cross and the vertically aligned stars Alpha Centauri and Beta Centauri already shine proudly above the clouds. The ALMA antennas already point towards a target object. Under the thin purple clouds, which have been regarded as a favorable sign from times of old, they seem to promise the realization of meaningful observations.
