Approximately 50 red circles of lights, travelling in a northerly direction. Some clusters; variations in speed and position. Noticed approximately 50 red lights travelling from south to north in the western sky. Objects were silent, flew in slightly irregular patterns and there were several clusters of 4-5. This continued for at least 20 minutes from when I first noticed them.I had my husband come out to witness this and he was as bewildered as me. The circular red lights were all travelling in the same direction and at similar, but not exactly uniform speeds. They all disappeared at a particular point in their travel northward. It was hard to tell if perhaps they were obscured but cloud cover but we did notice that stars were still visible in the area where they were disappearing.Surely this was seen but many many others. Hoping to hear news of what these actually were.
