Aftershock to yesterday's small quake on Arizona - Nevada border

There was a magnitude 2.0 earthquake at 2:55 a.m. local time this morning close to yesterday's M=2.3 and 1.8 quakes.    Was this an aftershock?    I'm not used to seeing earthquakes as small as M=2.3 generating aftershocks, so it may be just coincidence.   [Right, today's epicenter marked by orange star.
