| Summary:
Mini-EUSO is a wide Field-of-View (FoV, 44$^{circ}$) telescope currently in
operation from a nadia-facing UV-transparent window in the Russian Zvezda
module on the International Space Station (ISS). It is the first detector of
the JEM-EUSO program deployed on the ISS, launched in August 2019. The main
goal of Mini-EUSO is to measure the UV emissions from the ground and
atmosphere, using an orbital platform. Mini-EUSO is mainly sensitive in the
290-430 nm bandwidth. Light is focused by a system of two Fresnel lenses of 25
cm diameter each on the Photo- Detector-Module (PDM), which consists of an
array of 36 Multi-Anode Photomultiplier Tubes (MAPMTs), for a total of 2304
pixels working in photon counting mode, in three different time resolutions of
2.5 ${mu}$s, 320 ${mu}$s, 40.96 ms operation in parallel. In the longest time
scale, the data is continuously acquired to monitor the UV emission of the
Earth. It is best suited for the observation of ground sources and therefore
has been used for the observational campaigns of the Mini-EUSO. In this
contribution, we present the assembled UV flasher, the operation of the field
campaign and the analysis of the obtained data. The result is compared with the
overall efficiency computed from the expectations which takes into account the
atmospheric attenuation and the parameterization of different effects such as
the optics efficiency, the MAPMT detection efficiency, BG3 filter transmittance
and the transparency of the ISS window.
