Lots of awesome portuguese youtube videos surfaced after my first report. Search : " luz sobre bahia" . The state of bahia is across the river from my hotel the Nobile Suites in Petrolina in Pernambuco State. My theory is that it was rock that bounced off atmosphere. This city has lots of cams you can review. It was seen by many about 18:32 local time or 16:32 EST.
