Björn is right that making reference to nearby stars helps to ID a
UFO. In those instances it is proper to note what constellation a sat
is moving through.

I believe though, that  Bruno is talking about ordinary sightings such
as 'Mir crossed above star X'. If not comparing magnitudes, the star path
is a strictly local circumstance and I've also wondered why that 
unnecessary info was posted.

So observers, if you're trying to ID something or comparing brightness,
mention reference stars. Otherwise, it's better to give just az/el.

Do you agree B & B?
