I'd say it was as bright as the sun, but about 1/20th of the size.

Remarks
Super bright! Way brighter than Venus in the morning. (I thought a plane was going down at first). There was still a fair amount of light in the sky - you wouldn't be able to see a shooting star unless it was big - especially that low on the horizon.
