Summer is upon us, and three exciting live Pokémon GO events are just around the corner! These celebrations are happening in locations all over the world, but even if you're not able to make it to one in person, you'll still be able to participate in Professor Willow's Global Challenge. For the purposes of this challenge, the global community will be split into four areas: the Americas; Europe, the Middle-East, and Africa; Asia-Pacific; and the main research site (the location of the live event).
During the weekends of Pokémon GO's special live events, there will be new Field Research tasks to complete. If all four areas work together throughout the events and meet their goals, amazing bonus rewards will be unlocked. As an extra incentive, if the bonus reward is earned in all three summer events, a mysterious Ultra Bonus will be unlocked!
