Well, the Baffin Bay event finally showed up in the cnss_14_fing list of 
events that is accessible from within Winquake, and the surface wave
arrivals match my event pretty well.  I'm a little surprised to see so 
much high frequency energy, given the distance (almost exactly 2000 
miles straight north of me).  But, I don't see any other plausible 
candidate.  That list includes events as low as 1.0 and it's kind of odd 
that this relatively prominent event took so long to get posted.  So 
far, it hasn't been included in the NEIC list for some reason.

For some reason this event is not recorded by USGS?
  


  
  
I even recorded it on a 4.5 Hz geophone from Washington, DC.

Yesterday, at around 16:50, I recorded an event that looked like it was

relatively close to me.  It showed up in both the LF and HF channels of

my SG sensor, but is much more prominent in the HF channel.  It also

shows up in the data from all of the stations in the network of which

the Lamont-Doherty (PAL) is a member, again much clearer in the HF

records.  So far at least, it hasn't been reported in any of the

listings that I am familiar with.

    

Did anyone else snag this thing, or know what it was?
