The online image database contains images from up to seven all-sky
camera (ASC) stations since 1997. For data
availability, see the ASC keograms
and the availability catalogs. The time resolution
is 20 s for green (557 nm) and 60 s for red (630 nm) and blue (427
nm). Only those passages of images that might contain auroral
forms according to certain automatic criteria are stored online. If
your event is not found online, it is probable that no useful auroral
images exist.

timing and orientation errors. See also the interface
