Brief Abstract Summary
The work is based on the nadir observation of the SPICAV IR/VEX spectrometer. The dataset (>800 sessions) accumulated in 2006-2014 allowed to analyse the local time and latitude distribution of the O2 (α1Δg) airglow at night. The result extends the long-term and latitudinal coverage of the VIRTIS-M/VEX experiment almost to the entire night-time hemisphere. It is in correspondence with the previous ones, and shows the maximum intensity of 1.6-1.7 MR in the anti-solar point.
