Abstract
The Fluorescence detector Array of Single-pixel Telescopes (FAST) is a next-generation cosmic ray experiment aiming to observe cosmic rays above 30 EeV with unprecedented statistics. To achieve this, FAST will utilise low-cost, easily deployable, autonomous fluorescence telescopes
spread over a detecting area an order of magnitude larger than those of current observatories. We present the analysis of data taken by the current FAST prototypes in the northern and southern hemispheres between 2018 and 2024, including preliminary measurements of the energy spectrum and elongation rate from events observed in time coincidence with the Pierre Auger Observatory and Telescope Array experiment. We also briefly report on the development of the second-generation prototype telescopes and their scheduled installation as part of the FAST mini-array.
