Planetary defense-related activity program at Baja Observatory

Under MTH acronym ('Hungarian Bolide-observing Network') we installed a new allsky-camera system in 6 sites around the country, well covering the whole atmospheric ranges above Hungary. Each station has a multiple-camera head on the top of some building, having 7 (or in some cases 8) identical CMOS cameras, with low-distortion lenses, GPS sensor, control electronics, under a weather-proof acrylic dome, microcomputer, and UPS power supply. The hardware and software are developed by Mike Hankey (USA) and Sirko Molau (Germany). The camera system is coordinated by two of us (JZ and KZs), but all stations have local assistance. The main aims of our staff is calculating the atmospheric path and Solar System orbit of all fireballs detected by our system, deriving the possible strewn field, and trying to collect as many fallen meteorites as possible. Under the EON acronym ('European Optical Network') we installed a satellite tracking telescope system at Baja Observatory. The Celestron 11" RASA optics is equipped with a QHY268M CMOS sensor, and used on a PlaneWave altazimuthal direct drive mount. The regular observations were started in late October 2022. Until now we completed more than 120 hours observations of test satellites, and real targets, as well. The SST project will continue in 2023-24 adding a new feature to the observations: we shall install a 4-OTA's telescope system in a remote observing site for making multicolor photometry of selected space debris and active satellites, aiming for the possible characterization of these objects.
