A new measurement of the Cosmic Ray Electron and Positron spectra in the energy range of 20 MeV–1 GeV will be presented. The data were taken during the first flight of the balloon-borne spectrometer Anti Electron Sub-Orbital Payload (AESOP-Lite), which was flown from Esrange, Sweden, to Ellesmere Island, Canada, in May 2018. The payload collected over 130hrs of exposure at an average altitude of 3g/cm^2. The instrument incorporates a gas Cerenkov detector and a magnetic spectrometer to identify particle type and measure the energy.

Disturbances from the Sun often referred to as “space weather”, cause geomagnetic storms that can affect critical infrastructure on the ground such as navigation systems, high-voltage electric power transmission grids, and pipelines. Understanding the dynamic response of the coupled solar wind-magnetosphere-ionosphere system to severe space weather is an on-going challenge. This talk will highlight some of my past and on-going applied space weather research efforts and how this information can be used to address societal needs.
