Diego, the gray whale who took a wrong turn at Point Loma around March 10, was spotted three times in San Diego Bay Sunday.
The roughly 30-foot juvenile whale was spotted near the San Diego-Coronado Bay Bridge between approximately 11 a.m. and 1 p.m., U.S. Coast Guard Petty Officer Brian Ramirez said.
Diego was seen Saturday afternoon at the Berkeley ferryboat museum on the Embarcadero -- the first sighting since Wednesday.
Experts have said the whale appears healthy and have resisted efforts to try to herd Diego toward the open ocean out of fear of putting him under unnecessary stress.
The U.S. Coast Guard has been warning boaters to stay at least 100 yards away from the whale, even though he has created something of sensation for tourists on sightseeing boats.
The Coast Guard stopped monitoring of whale's whereabouts on Monday, pending any further requests from the National Marine Fisheries Service.
Wildlife officials hope the whale will soon find its way back into the ocean to join its fellow grays on their annual migration from the lagoons of Baja California, where they calf and mate in wintertime, to Alaskan waters, where they summer.
