Spotlight hour this Tuesday is rumored to be Surskit! You'll earn extra XP (and who doesn't want to level up sooner?!) for any Pokémon you catch between 6:00 p.m. and 7:00 p.m. local time.
Use 2 Lucky Eggs at 6:00 p.m. for double XP, then add any raids you see to GoRaidGo, beat the raid bosses, and earn quadruple XP when you catch the boss! (For even more XP, make sure to perfect those Excellent throws)!
