High-resolution UV/optical/IR imaging of Jupiter in 2016-2019 with HST/WFC3 and Gemini/NIRI
Abstract
Imaging observations of Jupiter with high spatial resolution were acquired beginning in 2016, with an approximate cadence period of 53 days to coincide with the atmospheric observations of the Juno spacecraft during each perijove (PJ) pass. The Wide Field Camera 3 (WFC3) aboard the Hubble Space Telescope (HST) imaged Jupiter in scattered sunlight from 236 nm to 889 nm in 9 distinct filters. The Near-Infrared Imager (NIRI) at Gemini-North collected images of Jupiter's thermal emission using a lucky imaging approach, in the M' filter centered at 4.7 microns. An archive collection hosts science products from this effort (doi:10.17909/T94T1H). In this presentation, we will examine changes in Jupiter's equatorial zone (EZ) during the span of the Juno mission. We will use stable HST photometry to measure changes in EZ color and cloud structure, and correlate high-resolution 4.7-micron and visible data to study the morphology of specific bright equatorial features in the thermal infrared.
