I made some videos to help compare the background motion frame by frame before / after the zip off. I used the frames from the 25% slowed down portion as suggested above.
Here I've compared the frames just prior to the zip off to get a baseline...
This video demonstrates an objection to the camera-motion hypothesis posited by Marik von Rennenkampff, on X.
He notes that the camera-relative trajectory of the object changes and suggests that this implies it is independent of the camera...
Seems like this one is a great illustration of the whole phenomenon, but slower. There is an attempt to track the object resulting in the object and the camera being synced up in relation to the background. When the tracking stops, the background...
PR078, a pattern is emerging....
Loss of lock, blinking, then zip-off as the camera changes direction. I think this is pretty definitive at this point.
The reason for the broken dashes of contrails is simple, but something often not seen from the ground. Air layers, perhaps one moist and the other dry, or one cold and the other warm, can meet each other in a ripple pattern, and a plane traveling...
I was just coming in to make the same point
Short, isolated contrail segments are usually caused by an aircraft briefly passing through a thin layer of very cold, ice-supersaturated air where contrails can form or persist, while the surrounding...
@Curiousfi could it have been a rectangular contrail? (short for condensation trail)
Rectangular contrail photo from 2022 Reddit thread:
This 2014 Metabunk thread by @Mick West discusses a news article about a rectangular contrail spotted in...
Same here, eagles moving into a nearby heronry. I was once watching the colony when two eagles wheeled in, and the herons immediately broke into a loud chorus that I can only interpret as "Lock up your children, there goes the neighborhood!". The...
This thread by @Adriaan is reminiscent of another recent thread by @nightsky74. Both are photos of angularly small objects, not noticed at the time. Object resolution is too low to positively identify. Such an object may range from large and...
Instances of "I didn't see it at the time, only when I looked at the pictures later" pop up regularly.
I think the issue is usually that the photographers eyes were focused on something very far away. So the insect quickly passing by, only feet...
Recently I published Polish article: https://ufonapowaznie.pl/ufo-z-kumburgaz-w-turcji-problematyczny-przypadek/ about this case (there is option in menu for translate). It doesn't really help with identifying the objects. It focuses on...
I just asked Villarroel for her take on the Greiner paper, and this is what she wrote (translated from Swedish):
"The original photographic plate containing the nine transients has actually been examined recently, and the objects are there and...
