Geographical and moon phase relationship of the uv and red-ir luminous events detected by the tatiana 2 satellite

Abstract:

We present preliminary results of the analysis of data taken by the Tatiana 2 satellite over the period from October 20, 2009, to January 27, 2010. The geographical distribution of transient discharges with energies larger than 1 kJ in the ultraviolet (UV), Red-Infrared (R-IR) wavelength ranges for the Full and New Moon phases and the correlation of these discharges with the fluxes of Charged Particles (CP) were investigated for first time using Tatiana 2 data. We found that UV events at New Moon phase are mainly distributed in the equatorial zone, while for Full Moon phase the events show a homogeneous distribution. UV and R-IR detections differ in duration and can show a variety of time profiles: from single short time flashes of ∼ 1 milliseconds (ms) to flashes with a complex profile of more than 100 ms duration. Measurements of the charged particle fluxes (with a threshold energy for electrons of 1 MeV) provide no evidence of synchronous occurrence with UV events. The CP fluxes show high values at the South Atlantic Anomaly (SAA). Remarkably, the CP fluxes distribution over the SAA is outlined by the magnetic field lines over this region.
