The October 14, 2023 annular solar eclipse was visible from the US Pacific coast to Brazil’s east coast. NASA’s Global-scale Observations of Limb and Disk (GOLD) mission observed the first synoptic thermospheric temperature changes from a geo-stationary orbit above 47.5°W longitude between 17-20 UT during the eclipse. These daytime thermospheric changes were derived using GOLD’s disk FUV measurements. A significant decrease in the daytime disk temperatures (~ 100 K) was seen near the peak annularity compared to the day before (baseline). The temperature reduction’s spatial morphology is also like that of the eclipse shadow. Modelling simulations underestimate the eclipse-induced temperature decrease (expected ~ 30-40 K) by a factor of 2-3 compared to GOLD observations. These first of kind results provide new insight into the dynamic response of the coupled thermosphere and ionosphere system to transient solar events, including eclipses.
