Seminar Abstract:

In this seminar, I present recent scientific findings using far and extreme ultraviolet (FUV and EUV) solar and stellar occultations, and make the case that this seemingly overlooked technique has the potential to address a number of questions of upmost importance to the heliophysics community. Solar and stellar ultraviolet occultations provide a capability essential for advancing our understanding of the thermosphere and its coupling with the ionosphere and lower atmosphere. Advances over the past decade have demonstrated the power of occultations for measuring gravity waves and tides over large altitude ranges and across atmospheric domains. Additionally, occultation instruments measure neutral density in the thermosphere directly using technology that is readily miniaturized, making them ideal candidates for space weather monitoring sensors. Future missions for studying the thermosphere should include instruments specifically designed for occultations to maximize the quality of science measurements.
