From SWTORista.com:

“The Rakghoul Resurgence, better known as the “Rakghoul Event”, is a limited-time event in Star Wars: The Old Republic. This event happens sporadically, and rotates between the planets of Alderaan, Corellia and Tatooine. The event focuses on the outbreak of the Rakghoul virus, and during the event you’ll travel to the rakghoul tunnels that have been dug deep underground.”

This competition is based on a 1-week event, “Rakghoul Resurgence,” that runs from January 10 to January 17, 2023.

Ideally, you should take screenshots of the “mission complete” pop-up that provides your rewards, but if you accidentally click accept on the window, screenshots showing the mission completion from your chat window will also be accepted.
