HFLS3 was subjected to a follow-up campaign by other telescopes due to its high redness. It was found in the HerMES campaign, which also found other very red sources.<ref>{{cite book|last=Clements|first=David L.|title=Infrared Astronomy – Seeing the Heat: from William Herschel to the Herschel Space Observatory|url=https://books.google.com/books?id=L29YBQAAQBAJ&pg=PA185|year=2014|publisher=CRC Press|isbn=978-1-4822-3727-6|page=185}}</ref>
