| Zusammenfassung |
| We use THEMIS data from 2010-2012 tail seasons to collect observations of plasma sheet
oscillations with kinetic ballooning/interchange instability (BICI) signatures. Over seventy
observations with closely located THEMIS probes P3-P5 reveal that BICI-like plasma sheet
oscillations may appear at different magnetic local time. For these, we derive background
plasma sheet parameters such as BZ, δBZ/δx and plasma beta, and investigate solar wind
conditions. We also estimate the proper parameters of BICI-like oscillations such
as frequency and amplitude. Based on this, we search for a relation between the
background plasma sheet parameters and the proper parameters of BICI-like oscillations. |
