Hi Ted -

There is more than one way to do this - the easiest would be to look  
at your data and compute the incoming ray path.  If you have good P &  
S waves, you could also get a rough distance from your station.   
Another way would be to download the SAC files from HLID and MSO using  
the VASE program, which is available through IRIS.  You can then  
convert them to PSN format through WiNQUAKE, or leave them in SAC  
format.  Note that WINQUAKE can read a data set in PSN format, but not  
in SAC format.  With P & S wave data from all three stations, you  
could draw the arcs and see where they crossover.  That would be more  
accurate.

Since the event was visible at both HLID an MSO, I would not be  
surprised if the records are updated sometime today.

This appears to be a local event nearer to =

that you got a clear indication of the P wave first movement.  If =
so, have you plotted the incoming ray path to your =
