Hola Francisco

Yes, I think that this radiant near Algol is really associated 
with the September Epsilon Perseids (max 170 deg, rad. 050.2,
+39.4 Vel=64.5) as indicated from Peter Jenniskens. 
But from the new observational data results interesting the 
different velocity.
>From my video data, I obtained (7 meteors) RA 48.2 DEC +38.0 
as position of the radiant and a velocity of 56.0 km/sec. 
Now I have analysed my data (46 meteors) together with the 
video data of September 8/9 (47 meteors) by my near observer
Maurizio Eltri too (Venice Italy, Teff 9.208h from 182552
to 034159 UT). 
Now with 12 meteors which fitt to the radiant, I obtained the 
same best positional determination in RA 48.2 DEC +38.0 and a
velocity of 57.0 km/sec, still different from 64 km/sec.
