2018 Workshop: Low latitude space WX
Marco Milla
The first half of the workshop will address the general theme of space weather at low magnetic latitudes including topics ranging from ionospheric instabilities and irregularities (i.e. equatorial spread F) to plasmaspheric drainage and refilling to magnetospheric coherent scatter to solar sounding. The second half will be more focused, concentrating on a planning a NASA sounding rocket campaign in Peru anticipated for 2021. Potential sounding rocket PIs and co-Is as well as scientists with complementary instruments and models are encouraged to take part.

The equatorial ionosphere was once regarded as being isolated from much of the rest of the ITM system, exhibiting its own unique form of space weather in the form of a variety of ionospheric instabilities and irregularities mostly unique to the region, e.g. equatorial spread F (ESF). However, ESF has proven difficult to forecast reliably, and this paradigm is too limiting. It is now widely appreciated that ionospheric stability in the equatorial zone is influenced by external thermospheric and geomagnetic drivers. As we consider higher altitudes and consider the equatorial plasmasphere and magnetosphere, the isolation between latitude regimes becomes even more tenuous. New experimental capabilities at the Jicamarca Radio Observatory make it possible to examine the coupling of the equatorial ionosphere to regions below and above the F region as well as the coupling to the thermosphere, the plasmasphere, the magnetosphere, and the sun. This workshop seeks to explore the capabilities and the coupling.
