Earth-38

Earth Thirty-Eight is one of the many universes in the multiverse.

History
This Earth is one where the existence of alien life has been common knowledge for over a decade—in particular, the Kryptonian heroes Superman and Supergirl. Barry Allen accidentally traveled to this Earth while testing out a Tachyon device, but was able to return home with Supergirl's aid.

A few months later, Barry and Cisco traveled to this Earth to recruit Supergirl's help in facing the Dominators.
