Per the USGS site, just a little 3.7 rumbler.
Heard someone farther down the cube farm go "OH! We got a quake." just before I felt the rumbling. Took it about 5 seconds to peak, then 5-10 to subside.
By the time I was deciding to get out of the chair and duck-n-cover, the peak had already passed.
And I've already filled out a "Did you feel it?" report.
