Shiny Pikachu rates increased for Pokémon GO Community Day event

Multiple people have reported catching a Shiny Pikachu in the first hour of the event.

The Pokémon GO Community Day event, running for three hours on the 20th of January, has started in the Asia/Oceania region. Early reports have indicated that the Surfing Pikachu that spawns may have a higher chance of being Shiny. User Forever, alongside numerous reports on The Silph Road Reddit, has informed us:

There’s 20 people in my local group that has posted they’ve found one in the last hour.
It’s Shiny, but maybe hard to tell given only the slight colour change.

Are you planning (and able) to go out and about during Community Day?

Thanks to Forever for the tip.
