Saw it in N Texas between dark +15minutes and about 2:30 this morning. Really nice. I've waited since 2003 to see another from my front yard. I caught the big ones during that last solar max including the X27 flare auroras. This show came from a merging of several X-class flares in quick succession. There was an X5.7 today that may also give us a show in 2-3 days depending on whether it had an earth-directed component.
