As I said, it barely seemed to move. What movement was discernable seemed to be that it was moving northwards. It was to my west which puts it over Banderas Bay rather than the high hills to the east. The entire bay is surrounded by these high hills but the bay is 30 Km wide.
I agree that at first glance it resembles a party balloon but it just seems unlikely. Had it been a small party balloon it would have been moving towards me on the west breeze which was always around 20-25 Km/hr the entire week we were there. It just hung there as well, had it been tethered I would expect some side to side movement for such an oddly shaped object. BTW, this was taken at approx 11 AM
Pete Tar's photo partially matches it imo.
Does anyone have access to Mexican Notams for Feb1-6, 2014? If its a weather ballooon it would have been in the area of aircraft taking off from P.V. airport, north of the airport but planes often turned north over Banderas Bay while climbing out.
Then again maybe I, and the 20 people on the cuise up river with me, were fooled by the lack objects by which to discern distance and perhaps there was a residential area just beyond the thick mangroves along the river on that stretch.
On another note a plug for the Hard Rock hotel in Nuevo Vallarta. Had a blast, good food, good entertainment, nice pool and most of all no damn snow!
Anyway it is a bit of a mystery and thought I'd post it here. Party ballooon, advertising balloon, weather balloon and at the outside chance, a parasail on tether to a boat in the bay.
