First observations of ionospheric irregularities and flows over the south geomagnetic pole from the SuperDARN HF radar at McMurdo Station, Antarctica

In February 2010 a new SuperDARN radar began operation at McMurdo Station, Antarctica. The radar is the highest latitude radar of the SuperDARN network, both geographically and magnetically, and the observations have a different character than those of the auroral zone radars. One particular feature of note is the high incidence of observed backscatter. When ionospheric altitudes are above the solar shadow height, the incidence of observation is greater than 80% for a large portion of the radar field of view. This is indicative of the near constant presence of field-aligned density irregularities in the polar cap. This Journal Club presents first observations and some brief analysis of their implications..
