Details:
The camera is a Canon 1100D with fisheye lens. 30 sec. exposures almost all night. There were green airglow most of the night and around 3 am St. Elmo´s Fire showed at the end of one or two of the carbon fiber rods above the camera. Airglow is coursed by molecules torn apart (by UV radiation from the sun) and recombining in the high atmosphere. St. Elmo´s Fire is coursed by electric fields in the air, electrons are ripped apart from the air molecules/atoms, producing purple plasma like you see in lightning (as far as I understand it).
See the time-lapse video and look at the rods at 3 am: https://youtu.be/HhRffy8nRyk

How high off the ground is this camera mounted? You are lucky not to have summoned a lightning strike directly onto your camera!! (amazing video btw)
