Buckie lifeboat and Burghead coastguard team were tasked late last night to reports of an activated distress flare near Hopeman.
A call was received from a member of the public around 11.40pm with both teams sent to investigate.
A coastguard spokeswoman said that despite searching for more than two hours, nothing was found by either team.
She added: “We are not certain if it is a distress flare.”
The teams stood down around 2.20am.
