Is this morse? Makes no sense
I saw a light blinking under a flag from afar at Holden Beach, NC (not sure if the location/context is useful information). It was 5 short 3 long over and over. When I looked up Morse code, it would apparently mean 5o5o5o5o, and so on. Which isn't a word obviously but also doesn't seem to mean anything according to the results on Google. I'm so curious and also a bit worried that it means something happened (I know the standard emergency signal is sos and is 3 short 3 long 3 short so this would mean something else).
