Star gazing in the yard at the time. Amateur telescope viewer and nightly sky watcher. 1st noticed the objects incredible silent speed. I instantly thought ufo as I've been able to research all of my previous nightly encounters to date and have been able to dis/prove all of them within a few weeks. I will not pursue any investigation to this as the answer is clear as to what I saw, however you may enlighten me. Large, silent, hazy, white light of oval/elongated shape moving in a straight line from the NNW to the SSE at a very high rate of speed East of Sand Lake Mi. The shape seriously reminded me of the typical "saucer on a string" from the 1960's movies. I adjusted my position away from tree line interference and the object went into a weaving/bobbing pattern in the SE, similar to what someone with a laser can do and at that speed but not distance or size. Again, this is at high speed and a larger light than I've ever seen in the sky. I readjusted my position again to confirm what I was seeing. After 3-4 minutes total, I lost the object to the horizon or possibly clouds. The weather was partly cloudy however the sky was clear in the area where I first noticed the object. I reacted like it was an everyday event as I am surprised it took me this long to see an unexplainable object due to my love of the sky. I reported it to NUFO almost instantly. Sorry about the delay with you. Approximate time of event was 12:50 a.m. 9/19/2015.
