It could also be that AO-7 is still magnetically stabilised. At high 
latitudes the bird might experience a rapidly changing magnetic field 
direction. Try looking for a piece of software called geomag and then 
plug in AO-7´s location. If the local magnetic field is pointing at the 
sun the bird is probably end on to the sun. One of my to-do projects is 
running the numbers on this (it will be slow if done manually). If 
someone has a copy of STK with the right plug-ins it will be quick :-) .
