Nocturnal means of airglow intensity for the O2(0-1) Atmospheric band at El Leoncito (32°S, 69°W), in 2002-2003. Note the untypical seasonal behaviour from March to mid-April. Intensities since November (in cyan; preliminary) have been adjusted for a 50% sensitivity loss suffered at the end of October. The intensity burst on Dec 1 is the first such event, in summer. The green line here corresponds to the climatology explained in Reisin and Scheer (2009).
