Now that it’s August, a new set of “Shared Skies” Timed Research has entered the fray in Pokémon Go.
This set launched on Aug. 1 and runs until Sept. 10, and it rewards Machop, Cubone, Hisuian Sneasel, and Donphan encounters. You’ll have to take out a ton of Team Go Rocket grunts in order to complete this set, so keep your eyes out for balloons and overtaken PokéStops.

Thanks to LeekDuck for helping flesh out the above steps.
As noted, there is a time-gated element to the final task — catching a Pokémon on 10 different days — so make sure you do this on Sept. 1 at the very latest if you want to complete every step and earn the final rewards.
