Hi All,

Thanks for the comments.

It turns out that it was a local quake, originating about 7.5 km from this station.   Magnitude 2.0, 21.1 km deep.

I posted about 6 hours after the quake.   It took longer for the UW seismologist to post the quake on their website found at http://spike.geophys.washington.edu/recenteqs/Quakes/uw05301656.html

Hello All,

I and* ELL SHZ UW : Ellensburg, WA* recorded an event, but none of the 
other Washington seismic stations on the web recorded it.   I am 
wondering what it might be?

My recording is at 
http://www.seismicnet.com/cgi-dos/makegif.exe?/quakes/0605/060530.165536.ebgz.psn

The UW recording is at 
http://www.pnsn.org/WEBICORDER/PNSN/ELL_SHZ_UW.2006053012.html

I do not know exactly where *ELL SHZ UW : Ellensburg, WA* is located but 
I believe it is 5 or more miles away.

I wonder if it might be a meteor?

Roger
