On the night in question we witnessed a triangular craft over the tree line close to my house. at first i thought it might have been a plane but there was no sound. it travelled along a very similar flight path to out aircraft locally. it was an oblong triangle with the top point longer than the sides. it was changing in colour from red to blue to white, pulsating, the ends and the edges. it then travelled slowly a few kms west crossing our bay and.Stopping over the land opposite. at that point we noticed multiple objects varying in distance and location. we have observed similar activity the last few nights. when they move, they move downward upward and side to side but not in straight lines. we have seen one seem to interact with a red light that came in from the right. we will attempt to record one or more objects this evening weather depending.
