Spark or Sierra: Your Pokémon GO Research Pick

Author : Aaliyah Update : Jan 23,2025

In every Pokémon GO branching research quest, trainers face a decision. This time, Pokémon GO offers little guidance on whether assisting Spark or Sierra best aligns with Holiday Part 1 objectives.

Pokémon GO Holiday Part 1 Branching Research Timing

Surprisingly, Niantic's official Holiday Part 1 announcement omits the free event research, mentioning only Field Research and the paid Timed Research. However, a free research path is available to all trainers, running from December 17th to December 22nd at 9:59 AM local time.

This "Holiday Part 1" research features three sections. After completing the first, players choose between aiding Team Instinct's Spark or pursuing Team GO Rocket's Sierra. Which path should you select?
