What is this violet colored spread in the sky?

Today on my way from Madison, WI, USA to Minneapolis, MN, USA on highway I94 I saw sky light up with violet color. Timestamp on my picture is at 6:48 PM. It's very strange. I do not think it was northern lights, too soon to hop on alien story. I know this could be due to some lights, but it was so bright and spread across such a large area, its stuck in my head. I am attaching pictures. Not very good quality as I was driving.



Let me know if you guys have any guesses. enter image description hereenter image description here

    @NeanDerThal - that would only be true if it was accompanied by a loud humming sound and his car and all electical devices in it suddenly lost power. Otherwise, no. The real reason is much simpler. Minneapolis is the former home of the former rock star formerly known as Prince, who was famously associated with the color purple. This is just a haunting. Nothing to worry about.

A greenhouse!



I know, but bear with me. Many on Twitter / Instagram snapped photos of similar lights, in recent times and in various places, and one of the sources was tracked down:




It turns out the mystery light came from a new, high-tech,
85,000-square-foot greenhouse on 76th Street near Hanna Lake Avenue
southwest of Dutton. The glow was the result of special purple LED
lights that can adjust to different spectrums to fit plants' needs.




Sources:




  • Purple glow in sky traced to greenhouse lights

  • Why Was the Sky Purple

  • Alien invasion? Not so much. Purple sky came from greenhouse lights


It's been reported in several places around the country, and so far at least, always comes from greenhouses with these LEDs.

    I think I was confused by your phrase "snapped photos of it". I made another edit to try to clarify further. Feel free to roll back if you don't like it.

    Wow, the overall efficiency must be pretty bad if so much light is sent to the atmosphere. And as an amateur astronomer, I'd be really angry at such a disturbing light source.

    @Tim No matter where you come down on the EU, the odds that they decided to restrict a single local USA news site by intercepting HTTPS traffic and somehow translating it to a 403 response .. are vanishingly low. More likely the site is georestricting its users to prevent spending lots of money on bandwidth serving those outside of its core audience.... or it's just having a technically bad day.

    @LightnessRacesinOrbit To clarify, I meant a restriction on the part of the site owners for EU users, possibly because of GDPR. They would not be the only site to do that.
