Teardrop over Colby (south of), WI

The report, as filed

My mother was driving my teenage brother and I (23 years old) coming back from Marshfield, Wisconsin, just south of Colby, I was lazily gazing out the front passenger side window, when I spotted a vibrantly bright emerald colored teardrop shaped light with a golden/orange sparking trail about 350ft to 400ft up and about 250 to 300 yards away from the road we were driving on. At first I thought it was a shooting star and i shouted for my little brother in the back seat to look because my mother was driving, but it moved too slowly for the first few seconds to be a shooting star and then in the blink of an eye (a split second) it shot away from us (rough estimate) 65 degree angle and disappeared. The strangest thing I noticed was that the emerald green light looked different than a light you normally would see at night. It had no glare or beams of light coming off it like a street light at night normally would. It was a solid green teardrop shaped ball of light abo! ut the size of a bowling ball that was extremely bright and yet had no light emanating from it. The trail looked to be 4 1/2ft to 6ft long from our location with a very slight downward curve. It was solid white in the center with golden/orange sparks surrounding the center. The trail was thicker at the end and only slightly narrower towards the emerald light. The sparks seemed to be falling off the trail. We have amended the time above, to reflect a nighttime sighting.
