((ADDENDUM FROM WITNESS))
I just looked at a star chart app, I think you may be right about Sirius... very sorry about that one, but 2010 i have my son as a witness for those 3 objects.
((END ADDENDUM))
Approximately at 9:15 PM/21:15 hrs I had walked by my window to get my phone off the table, my picture window faces east, I am very familiar with the night sky here as there is no light pollution, or yard light and live in a isolated area, I had noticed in the south east hemisphere a oval shaped object with blue, white, red and green lights, I noticed the colors as odd as one would see a car pulled over by law enforcement, it was that color of blue that caught my attention, but this was in the sky, I took my 3 dogs out as it was time to let them relieve themselves, so I had a few minutes outside to observe this, these lights were flashing, I am familiar with airplanes, this wasn't a airplane, I studied aerospace manufacturing in school, this hovered, and it was hovering for approximately 10 mins since I got there (outside) and until I brought the dogs in, I have a high powered scope on my rifle, and set my rifle on the table and found the object in my scope, I had zoomed in 20x on it, I supported the rifle steady with the Bipod as so I can observe movement, I observed the object approximately 7-8 minutes and it started to ascend in a south east direction until it dissapeared out of sight, I live not far from the U.S border, it was heading towards the Minnesota state area, but still ascending at a steady rate.  This I believe was not man made, it was approximately a mile and half from my window, height in the sky unknown but if I looked above the treeline half a mile away it would be at almost a 35 degree angle from my line of sight.  This is my second encounter, and I am an avid night sky watcher, this just happened and am reporting this whilst it's still fresh In my mind.
Possible sighting of Sirius?  PD
