Spotlight Hour is a weekly event in Pokémon GO that highlights a specific Pokémon for a one-hour period. During this hour, the featured Pokémon will appear more frequently in the wild, giving you an ample chance to catch them and stock up on candy.  

Spotlight Hour takes place every Tuesday evening from 6:00 PM to 7:00 PM local time.  

In addition to increased spawns of the featured Pokémon, there is also a special bonus in effect during Spotlight Hour. This bonus varies from week to week.

Here are a few tips for making the most of Spotlight Hour:

• Stock up on Poké Balls and other catching supplies. You'll be encountering a lot of the featured Pokémon, so you'll want to make sure you have enough Poké Balls, Berries and more to catch them all.
• Use Incense and Lure Modules. These items will attract more Pokémon to your location, which can be helpful for catching even more of the featured Pokémon.
• Take advantage of the bonus. The Spotlight hour bonus will change from week-to-week, so make sure you are taking advantage of the bonus results and using special items like Star Pieces, Lucky Eggs and more to make the most of the bonus while you can.
