There's still no explanation as to the source of the mystery plume that showed up on area radars Monday.
The radars first picked up the plume in Socorro County Monday evening. The plume then headed east into Texas and Oklahoma.
According to Holloman Air Force Base near Alamogordo, the plume was not a result of a White Sands Missile Range defense test mission, nor was it an explosion.
KOB eyewitness News 4 is still looking into the cause of the plume.
