Educational satellite Lomonosov with the DEPRON instrument onboard was launched on April 28, 2016 from the Vostochnyi into sun-synchronous orbit about 480 km altitude, the main objective of the mission is to study the transient phenomena in the Earth's atmosphere. After the in-flight tests DEPRON instrument operates in permanent mode as primary radiation monitoring device of mission. For the early 2017 it has nearly a half of the year power up time. Figure 1 shows data received in August 2016, special interest was accepted to spikes, believed to be a significant rising of high-energy electrons flux i.e. relativistic electron precipitation (REP).
