Full Description & Details

about 1 hr after dark wife and I saw 4 strobe lights flashing in rapird sequence in straight line. distance between individual lights about 3 to 5 arc sec of sky with total darksness in between. lights stayed evenly spaced.no sound heard. Moved from se toward nw. I picked object up 40 deg above se horizon and followed it until it disappeared to the nw. About 40deg above the ne horizon it smoothly and suddenly changed shape from a linear formation to a cresent shape and continued to move that way. Iam a the physician, aviation enthusiast, ameuter astronomer. I have never observed this type of object. I called the local news they denied any similar reports.the space shuttle(movesE to W) was up at the time.

Can sighting be explained as any conventional man-made or natural object?

baqssed on my past experience no to all of the above

Views on UFOs, before and after sighting

there is life else where. I seriously doubt they visiting here or the gov is covering other worldly presence up. that said I cannot reasonably explain what my wife and I saw.
