The Hydrogen Epoch of Reionization Array (HERA) is a radio telescope dedicated to observing large scale structure during and prior to the epoch of reionization. It is set in South Africa, next to where MeerKAT is (the Karoo desert). When complete, it will have 350 dishes, each of 14m diameter. It is the most sensitive radio telescope at the moment to probe the Epoch of Reionization, operating at frequencies between 100 MHz and 200 MHz. The Center of Radio Cosmology is a member of HERA.
