A large solar flare on Thursday was expected to lead to heightened aurora activity this weekend but not as far south as Colorado. One Thornton resident however appears to have captured images of the northern lights Sunday morning.
The images by Justin Whitesel show a purple sky over the city as the geomagnetic storm hits the Earth. You can view an animation Whitesel put together here.
The tornado that touched down in the Denver suburb of Aurora and caused damage to a local mall and apartment complex has been rated an EF1 by the National Weather Service. After two days of evaluations, the service said that the twister most likely had winds of 100 mph, placing it in the middle of that rating.
The four other twisters that struck the area will be rated later this week. Because they were short lived and struck in open areas, they mostly likely will be rated as EF0 twisters with winds from 65 mph to 85 mph.
The other tornadoes were reported in the area of 144th and I-25, one was reported five miles south of Bennett, one five miles south of Deer Trail and one three miles north of Byers.
