Large cigar shaped craft flies overhead slowly then disappears.

While standing in the parking lot at Smith’s Castle, a large cigar shaped craft appeared in the sky above us. The whole craft emitted a white glow and moved very slowly overhead. The sky was mostly clear with an occasional cloud passing by. After about 60 seconds or less of observing the object it seemed to have just “blinked” out and disappeared. I tried to film the sighting but it did not pick up on my iPhone (which I found strange because it was fairly bright and close).
