Pokémon GO Rings in Sky Explained

Players might have noticed that there are unexplained rings in the sky following the start of Pokémon GO's Ultra Unlock Part Three: Sword and Shield on Friday.
The rings were also prominent both in the video trailer for the Ultra Unlock bonus week, as well as during the final day of the Pokémon Fest 2021. The rings themselves are said to be made by a mythical Pokémon named Hoopa that is known to bring Pokémon from other games into the Pokémon GO world.
At 2am on GO Fest Day 2 the sky changes to the special GO Fest event sky.

Players should expect to continue seeing the mysterious rings in the sky until the end of the Ultra Unlock event on Aug. 31. As Hoopa is known to bring in mythical Pokémon, players should be on the lookout for a potential new Pokémon to make an appearance before the end of the event.
During the event players can also be on the lookout for a full range of Galaraian Shiny Pokémon, as well as new Gym Challenger uniforms and stickers to collect. Pokémon such as Zacian, Zamazenta, Wooloo, Skwovet, and Falinks were also introduced for the event, so players have a lot activities to participate in for new Pokémon.
