  AMICal sat, a dedicated 2U cubesat, has been developed, in order to monitor
the auroral emissions, with a dedicated imager. It aims to help to reconstruct
the low energy electrons fluxes up to 30 keV in Earth auroral regions. It
includes an imager entirely designed in Grenoble University Space Center. The
imager uses a 1.3 Mpixels sparse RGB CMOS detector and a wide field objective
(f=22.5 mm). The satellite platform has been built by the polish company
Satrevolution. Launched September, 3rd, 2020 from Kuru (French Guyana) on board
the Vega flight 16, it produces its first images in October 2020. The aim of
this paper is to describe the design of the payload especially the optics and
the proximity electronics, to describe the use of the payload for space weather
purpose. A preliminary analysis of a first image showing the relevance of such
an instrument for auroral monitoring is performed. This analysis allowed to
reconstruct from one of the first images the local electron input flux at the
top of the atmosphere during the exposure time.
