Details: traveling eastbound on route 2 in gilman, ct @ 65mph at 9:53 pm est 7 may 2020. no road lighting, no traffic at all for at least 2 miles, no lighting whatsoever except from the moon. completely clear sky and excellent visibility conditions. no debris on windshield as i had washed my vehicle the day before. vision is better than 20/20. zero hindrances to line of sight. event witnessed: a ball of white light with a bluish white aura around it suddenly seemed to ignite in the sky. it was very large, far larger than an aircraft (i work for the dod and am accustomed to seeing military aircraft, engines, etc - this matched none). by my estimate at the time it looked to be around slightly shy of half of what a full moon appears as in the sky, and was very far away. the circular object hovered briefly at a high altitude above where you'd expect cloud coverage (one second maybe), and then suddenly darted from south to north out of line-of-sight faster than any aircraft i'm aware of is capable of. unable to secure any footage or evidence as the event happened too fast to react to.
