What could be causing the unusual lights north of Jobos?

Have you considered it might be heat-lightning? NOAA has a page that explains it.

Those are a different kind of lightning that doesn't reach the ground. There are even lightning that move from the clouds towards space, or only occur within the clouds and don't touch the ground or the space. There are even balls of electricity that look like something out of science fiction. Some lightning can only be seen from space. Our atmospheres have many ions, where there are ions there are charges, and where there are charges there is electricity and where there is electricity there are lights.
