Triangle over Spring Hill, FL

The report, as filed

A few minutes past nine in the evening I was in the yard and noticed, to the west-northwest (over the Gulf of Mexico) several thunderheads. Behind them there was still some light and the sky was not quite dark, though nearly so. One only of these thunderheads, at about 340 degrees, was lit with a particularly brilliant sequence of lightning bolts, coming repeatedly every few seconds. As I watched it, I saw a plane (with its anticollision lights blinking) pass below between the thunderclouds and myself. And then, high up, seemingly at or a little above the tops of the thunderheads, I saw a white light moving towards the northeast. I thought it might be a satellite or very high jet, but then the single light resolved into three separate white lights, in a tight triangular formation. The object then slowed, reversed direction, then slowed, proceeded northeast again and went behind another high cloud. I waited for it to reappear on the far side of the cloud, bu! t it never did so. The object(s) must have been at a very high altitude, and it occurred to me that to see the three lights distinctly separate at such height must indicate large size.
