Dear sir!
13 Dec (AM) from midnight to 4:00 in my Observatory on the roof was installed four cameras to record the meteor shower geminid. All used roll film size 120 (size 2 l + 3 l +). Although this time, it was collected only three of a meteor, one of the winners of the Kodak (f3,5 focal length: 4 inches (lens wide open) recorded the attached unusual traces for (approximately, "EopJ" - p. 5) with period between 3 and 3:10 approximately.
This camera was facing South and at an angle of 45 degrees. Jupiter appears in the upper right corner of the print. Traces rise in the camera bottom. At a time when it was recorded, I changed the film in two cameras and stood with his back to the South and saw nothing.
Of course, I don't understand how something so bright had not attracted my attention, but apparently, the object or objects were silent. I've checked every possibility that could cause those marks, and I can't find a single one that would be consistent with the facts. Due to the blinking effect of some traces of course, I thought it was the lights of an airplane, but a study of several negatives on hand, made with the same cameras in the past, shows a completely different effect.
The main trails here are totally same bright as the image of Jupiter, which gives a good comparison. I was watching and photographing the sky for over 20 years and never seen anything like this before. Your opinion would be very helpful on this issue.
Sincerely, John T. Hopi

Summary: Photo Editor, Sky & Telescope Cambridge, ‘Mass. Dear Sir: On Dec. 13 (A.M.) from midnight to 4 A.M., T had four cameras set up in my roof-top observatory to record the Geminid meteor shower. All used 120 size roll film (2lt x 3l+” size). Although only three meteors were picked up during this time, one of the Kodak Medalists (f3.5, 4 inch focal length (lens used wide open) recorded the enclosed unusual trails during the (See “EopJ” – Page 5) b period between 3 and 3:10 approximately. This camera was aimed to the South and up at a 45 degree angle. Jupiter appears at the top right of the print. The trails rise into the camera’s field from the bottom. At the time this was recorded I was changing the film in two ol the other cameras and had my back turned to the South and did not see anything. Of course I don’t understand how anything this bright did not attract my attention, but apparently the object or objects were silent. I have checked every possibility that could have caused these trails and can find none that fit the facts. Due to the blinking effect of some ol the trails, I of course thought that they were aircraft lights, but examination of several negatives on hand taken with the same cameras in the past show an entirely different effect. The main trails here are fully as bright as the Jupiter image which gives a good comparison. I have been observing and photographing the sky for over 20 years and have never caught anything like this before. Your opinions would be most welcome on this matter. Very truly yours, John T. HopI
Hypotheses
Objects in motion, captured on a long exposure
Most often this artifact is called skayfish if the lens gets a passing bird or insect. It is based on the discrepancy between the speed of the video and the frequency of the flapping of insect wings. Essentially, each video drops a few strokes of the wings of an insect, which when viewed looks like "arrow", provided with long protuberances. The motion of the insect by its translucent body seems to "boom" and vibration of the wings give the appearance of bumps.
