    Abstract

    Energetic particles trapped in radiation belts were measured by Light Particle Detectors (LPDs) onboard two satellites, USERS and SERVIS-1. LPDs on USERS observed trapped protons with 15 - 130 MeV and electrons with 0.8 - 20 MeV in the inner belt for the period from September, 2002 to February, 2005. LPD on SERVIS-1 has been observing 1.2 - 130 MeV protons and 0.3 - 10 MeV electrons in the inner and outer radiation belt since November, 2003. It is found that the intensities of protons with 1 - 30 MeV and electrons with 0.3 - 2 MeV in the inner radiation belt at L < 2 rapidly increased after the flare on 28 October 2003 and then slowly decreased for many months. Furthermore, a new belt is found to be formed in association at L ~ 2 with large geomagnetic storms connected with big solar flares.
