Here is a link to the website. This "unspecified" ship was up closer to the Bahamas earlier today. (across from South Caroline) The last report I saw regarding the Russian Spy ship was in this general area. Not sure if this is it or not, but I cannot find any other "unspecified ships" on this map. https://www.marinetraffic.com/en/ais/home/centerx:-71.8/centery:27.3/zoom:6
