    Results of AllCola:
    
    Elsets #8 and #14 had a long sequence of encounters 2002-11-26 02-18 UTC
    
    #9 and #13 2002-11-26 21:59:02 at 4 km
    #9 with #14 and #15 2002-11-27  2:17:15 at 30+ km
    
    #14 and #15 2002-11-26 20:59:50 at 8 km
    
    So, if there was a single-impulse boost it would have been Nov.26 around 22:00
    UTC
