Pitch angle omnidirectional electron flux spectrogram in 1.8 MeV energy channel during 2014 September 12 between 17:40 and 21:00 UT. The electron flux dropout observed after 18:30 UT in pitch angles close to 90° seems to be due to magnetopause shadowing. The dropout in pitch angles lower than 30° and higher than 150° after 19:00 UT corresponds to pitch angle scatter into atmosphere.
