The instrument PEEL recorded low flux of precipitating energetic electrons during the flight of the HotPay-2
sounding rocket launched from Andoya Rocket Range (Lat. 69°.18'N, Long. 16°.01'E) on 31-JAN-2008 at 19:14:00 UT.
After the brief description of the instrument, its possibilities and limitations to measure energetic electron flux in the upper
atmosphere, the profile of counting rate obtained by the three detectors in four energy channels is presented. The epoch of
solar activity minima and relatively low geomagnetic activity preceding the HotPay-2 mission, the detectors with given
geometrical factor provided relatively low counting rate. Energetic particle precipitation contributes significantly to the
energy deposition in the ionosphere and thus its measurements on rockets are important for the updating of models used in
space weather forecasts. Such measurement device, can serve for space weather monitoring of energetic electrons present
in the upper atmosphere. This type of in situ measurements can contribute to the completeness of the picture of electron
flux (its high energy part) distribution and of its variability in the vicinity of Earth.
