I though it was supposed to peak around 6:00 AM.
According to the article:
In the early evening of Dec. 13, the radiant is low in the northeast. By 1 a.m. EST, after the date has changed to Dec. 14, the radiant is almost directly overhead. By 6.a.m. EST, when the shower is at its peak in the Eastern Time Zone, the radiant is low in the west.
Remember way, way back when I was a kid, we witnessed a Geminid shower that was probably over a thousand per minute about a 1/2 hour before dawn.
Haven't seen anything like it in 50 years.
