    Simone,
    I captured additional flashes of IRIDIUM 33 occured at my location.
    Long: 9deg 1min 26.6sec  E
    Lat: 46deg 13min 53.1sec N
    Elev: 260m
    
    All flashes of negative magnitude.
    I'm sorry for the NON-usual observational report.
    
    Date	Time UTC	RA(d)	De(d)	
    
    26jun	21:03:11	243 	63.5	
    26jun	21:03:02	243.5	67.5	
    26jun	21:01:53	62	86	
    26jun	21:01:45	65	83.5	
    26jun	21:01:36	64	81	
    23jun	21:05:15	267 	24.5	
    23jun	21:02:50	343 	74	
    23jun	21:02:42	351.5 	74	
    
    
    Time precision: + - 1s
    Coordinates precision: + - 1 deg
    
    I hope that these new data can provide useful information about the possible 
    reflection of the other reflective surface ( not the one observed in March).
    
    
    Regards,
    	Stefano
    
    PS. Seems the rotation period is around 8s ?
