The Benton County Sheriff's office received hundreds of call over night because an strange purple haze lighting up the Finley skies...what was it?

No it wasn't an alien invasion....here's what the Sheriff's office had to say..

From the Benton County Sheriff's Department:

What could it be!?!?
We have been receiving numerous calls regarding the large purple glow in the Finley area. Not to worry! It is just an extremely large greenhouse combined with the low winter cloud cover, making it visible from areas all over the Tri-Cities and Walla Walla County.
