Hello, I am the photographer of today's APOD.
First of all, I am sorry not to be able to write sooner. And below is what I can say about the image.
We were observing at Beynam, Ankara, Turkey (the location data can be found at
http://www.heavens-above.com).
The streaks in the picture you see comes from 5 different pictures I took, at 04:23-04:25, 04:31-04:33, 04:41-04:43, 04:51-04:53 ve 04:59-05:01 GMT+3, in the morning of 12th August (not 13th). I aligned the streaks according to the background stars they passed. (You can see the effects of composition in the picture.)
When the first meteor stroke, one friend said, "If you could not catch this, I will lose my respect in this photography," and we are sure it was a meteor. And we thought it to be a Perseid. Why not? It was the Perseid night.
When examining the images I came across the repeated streaks in the series (I took 100 of these pictures using the camera and lens combination you already know) it was clear that satellites were a possibility. (But we did see the first one as a meteor, remember.) I guess, either a satelite or a meteor, the streak cut right at the bright edge was recorded just at the beginning of the exposure, as the ones we saw were moving from left to right.
And we did see two satellites moving parallel, of one I later confirmed to be Iridium, not at the part of sky you see the streaks, but 25 degrees to the right, in Eridanus.
And, I found out other mentioned possible Alpha Ursae Majorid streaks in other images and "not in Orion". Had I not found those, I would be in much doubt, maybe never posting the image at all.
Last, I submitted the image data (and original images themselves) to Dr. Josep Maria Trigo, a researcher of these subjects.
I hope this helps. Good day,
Tunç Tezel
But still, I have 2 ot 3 more non-Perseid streaks in consistence with the radiant of this shower.
-- it's clearly a light shining on wires (the top wire being lightning protection, as usual).
