    After a long time for me, TDF 2 has appeared flashing here!  
    It has one of the shortest flash periods of this type of object.
    The last flash was seen with 8x42 on the previous night was at 
    4:25:24; the following was almost 20 minutes later.  I think 
    there was a 3/4-period phase shift before beginning the count 
    for the following PPAS report for it:
