Abstract
EUSO-TA is a ground-based telescope, located at the Black Rock Mesa site of Telescope Array (TA), Utah, USA. The main aim of the instrument is observation of Ultra High Energy Cosmic Rays through detection of ultraviolet light generated by cosmic-ray showers. EUSO-TA consists of two, 1 m$^2$ Fresnel lenses with a field of view of about $11^{\circ} \times 11^{\circ}$. Light is focused on the Photo Detector Module composed of 36 Hamamatsu multi-anode photomultipliers, for a total of 2304 channels. During operations, the telescope is housed in a shed located in front of the TA Fluorescence Detector. We present the results from EUSO-TA observational campaigns performed in years 2015 and 2016, including detected cosmic rays, meteors and laser shots. Also shown are the details of current instrument setup and upgrade of the detector to phase II.
