    In respect to Don Gardners obs I looked up my last obs of 99- 22C:
    
    99- 22 C 01-01-13 18:14:44   LB   47.1 0.2  10  4.71  AA, 4->5
    99- 22 C 01-01-15 18:14:12   LB   95.2 0.2  20  4.76  FF, 4->i
    99- 22 C 01-01-16 18:13:16   LB  144.1 0.2  30  4.80  AA, 4->i
    
    This evening I observed 99- 22 C and found:
    99- 22 C 01-03-12 19:40:21   LB  125.4 0.5  20  6.27  AA, 3->5
    
    In 2000 I made the following obs:
    99- 22 C 00-01-08 18:15:31   LB   52.3 0.1  60  0.872 FF, 4->i
    99- 22 C 00-01-09 18:18:37   LB   95.6 0.2 110  0.869 FF, 4->i
    99- 22 C 00-02-11 04:57:27   LB   67.3 0.2  70  0.961 FF, 4->i
    99- 22 C 00-03-12 18:41:55   LB   58.0 0.2  52  1.116 AA, 4->5, dtm
    99- 22 C 00-05-05 21:18:50   LB  161.8 0.2  80  2.023 AA, 3->i
    99- 22 C 00-06-30 21:43      LB                       S, 3
    99- 22 C 00-06-30 23:22      LB                       S, 4
    99- 22 C 00-08-24 02:42:37   LB   71.1 0.2  30  2.37  AA, 4->6
    
     When adding Don's obs to my own obs and running Satflash; the obs 
    fits nicely to the regressionline of the graph with r=0.9915
    So the slowing down continues regularilly. 
    
    Regarding 93- 61 A:
    On Feb 15 I observed it with P=6.60 sec measured on every flash. 
    This comes to 26.4  sec for the bright flash that normally occurs every
    fourth flash. So it is slowing down slightly.
