I might guess that they're star trails from a long exposure, but this photo must have been taken with a really short exposure to capture the lightning. My other guess would be a meteor shower, but I'm not aware of one around the date of that photo (September 27). Can anyone explain?
You already did. They are star trails. As for the lightning, a longer
exposure is more likely to catch multiple flashes, as in that photo.
Unless your shutter finger and your reflexes are literally as fast as
lightning, it's very hard to capture lightning with a short exposure.
