Nocturnal means of airglow intensity for the OH(6-2) band at El Leoncito (32°S, 69°W), in 2007. Intensities have been adjusted for consistency with data before November 2002 (because of photomultiplier change). Record-breaking "bright night" on June 22/23 (in midst of an unprecedented "bright spell" lasting five nights) surpasses all our previous "bursts" by at least 13%. The green line here corresponds to the climatology explained in Reisin and Scheer (2009).
