A pale light blue craft moving east, no navigation lights.

An obleque shaped craft was moving eastbound towards RNO at a consistent ominous speed (I first dismised it as a jet or plane) but noticed it didnt have
navigation or flashing strobe lights. It made no sound. I then thought it was a satellite, but it was far to low and under higher altitude cloud cover to be one. It was a blue orbish shape...just moving. It was about 5-7 miles from my eyes view (as far I could tell) I was looking from my third story deck, facing the downtown Reno skyline, with RNO to my east. The color was a pale electric blue, looked identical to a star in the nights sky. Again no flashing lights where seen on the craft, unless it was at a greater distance than I could've comprehend. After about 30-40 seconds of eastward travel the craft abruptly faded away it took about 3-4 seconds to completely fade/disappear into the night sky. My thoughts; not landing lights, why light electric blue and solid in color? why no nav lights/strobes? No noise? Looking forward to hearing some feedback on this one...
