The USGS posted this event =
http://earthquake.usgs.gov/eqcenter/recenteqsus/Quakes/us2009gpb2.php It =
was a 3.1 North of Boise 88km.

Thanks to Bob and others for trying to help me identify it.   I wanted =
to try to pin point the epicenter on my own, but was off by about 100km. =
  I had a very difficult time trying to determine the S on any of the =
five sensors we are running locally.  There are many remote stations in =
Idaho, but most of them are not maintained.   Hailey Idaho was avail, =
and that helped. This is a good example why good design and quiet =
locations are so  important.    At our stations the P and S were only 10 =
seconds apart and the S not well defined at all.  All this made accuracy =
very difficult.

Thanks, again
Ted
