How long will this solar show keep going?

Yep, 4th night of Aurora.  She did her typical quick tease at 8:30 pm with a bright band low on the horizon--just enough to make you think it's going to be another monster display but it quickly disappeared and didn't come back until 12:30 am this morning.  Not as bright as the last couple of nights, but another quick hit of pink around 1 am.  It's always fun just to be out there at that time of night when Bear Valley is almost silent, watching this energy flow across the heavens.
