I was driving home from taking pictures of the sunset at a nearby marina north of tracy, ca there were storm clouds chasing me so i was in a hurry to get some shots off of this tree in a silhouette with the lighted clouds behind it. i took five or six shots as the rain hit me. when i shot these i did not see anything out of the ordinary. until thursday morning when editing them in lightroom i seen a weird thing in the second shot that i didn't in the first. i thought the whisper of a cloud was a funnel cloud. the second picture changed my mind because the first was taken with my nikon d750 and tamron 15-30mm at iso 320 24mm f/2.8 0.5 sec at 8:03:22 pm and the second picture shot the very next second at 8:03:23 pm the second shot showed a shadow of something in the clouds the third shot five seconds later showed and object moving in the sky. i did not see any flying object and there was not flying debri floating in the sky from the storm. in the pictures you can see whatever it was made a ring in the cloud as went into it.
