What's going on here?

1) About 4 weeks ago, I spotted what appeared to be a fleet of Rhoden vessels all aligned somewhere on the Boystin gate in Oerse, Solitude.

2) Today, I am minding my own business when I notice what appears to be a beam of some kind connecting two stars (I presume they are stars) on the Oerse gate in Larryn, Solitude.

Does anyone know what was going on in case 1 or what is happening in case 2?
