A cigar shaped craft initially was spinning/pinwheeling about it's center emitting bursts of white vapor until it corrected itself.A spider filament had caught my eye, but the object well behind it. What brought it to my attention was the craft seemed to be spinning end for end about it's center and it was shooting out a white plume in sort bursts that disipated quickly. I was facing almost due west, the object was relatively close to the sun in the sky, but the sun's location was essentially south of the object, The object was about 40 to 45 degrees above the horizon. The sun reflected off the object, which made it visible for the duration of viewing, giving it the appearance of metal reflecting sunlight. It appeared to straighten it's attitude to an East/West orientation but at the same time appeared to be drifitng to the North and slightly East until it disappeared from view. The spin was tight- too tight even for aerobatic aircraft. No other aircraft were immediately in the vicinity. The craft also was silent. Width to length ratio was about 1 to 15.
