VVV-WIT-07 is a unique variable star which presents a sequence of recurrent dimmings (Ks~14.35 – 16.164)[1] with a possible deep eclipse in July 2012. The star, located in the Scorpius constellation about 23,000 ly (7,100 pc) away,[1] is not a binary star, which would eliminate such a system from explaining the various observed dimmings.[3]
