Date okay, but what has latitude to do with it? There is no reason at all why 
atmospheric entry of objects from the beta Taurid stream (if Tunguska was 
related to this stream at all!) would be restricted to high northern latitudes. 
In fact it is not even restricted to the northern hemisphere

The beta Taurid radiant was barely over the horizon (only a few degrees) and it 
was close to local midnight (albeit with midnight sun, yes).

Wrong. They only come from the radiant and move *towards* the anti-radiant.

Again: wrong. Tunguska for what we know of it went southeast to northwest. And 
fireballs from the same source for the Norwegian time and location should move 
northeast to southwest, not west to east.

Besides: the reports so far do really not give any clear clue as to direction of 
the Norwegian fireball.

I am curious to know whether the seismic data point to an airblast or a real 
impact (that is not yet clear to me). Not everything giving of strong sonic 
booms ends on the ground, you know.
