cds-question@unistra.frexoplanetshigh-velocity-starshst-photometryOptical reflected light eclipse observations provide a direct probe of exoplanet scattering properties, such as from aerosols. We present here the photometric reflected light observations of WASP-43b using the Hubble Space Telescope (HST) WFC3/UVIS instrument with the F350LP filter (346-822nm) encompassing the entire optical band. This is the first reflected light photometric eclipse using UVIS in scanning mode; as such, we further detail our scanning extraction and analysis pipeline Arctor. Our HST WFC3/UVIS eclipse light curve for WASP-43b derived a 3{sigma} upper limit of 67ppm on the eclipse depth, which implies that WASP-43b has a very dark dayside atmosphere. With our atmospheric modeling campaign, we compared our reflected light constraints with predictions from global circulation and cloud models benchmarked with HST and Spitzer observations of WASP-43b. We infer that we do not detect clouds on the dayside within the pressure levels probed by HST WFC3/UVIS with the F350LP filter (P>1bar). This is consistent with the general circulation model predictions based on previous WASP-43b observations. Dayside emission spectroscopy results from WASP-43b with HST and Spitzer observations are likely to not be significantly affected by contributions from cloud particles.2021AJ....161..269Fhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/161/269CatalogResearchIsServedByTAP VizieR generic servicerelated-toJ/A+A/563/A40 : WASP-43b g'r'i'z'JHK light curves (Chen+, 2014)J/PASP/127/143 : WASP-39b and WASP-43b light curves (Ricci+, 2015)J/A+A/594/A65 : GTC transit light curves of HAT-P-32b (Nortmann+, 2016)J/AJ/151/17 : Eight transiting light curves of WASP-43b (Jiang+, 2016)J/A+A/600/L11 : GTC transit light curves of WASP-52b (Chen+, 2017)J/A+A/616/A145 : GTC transit light curves of WASP-127b (Chen+, 2018)J/A+A/615/A79 : KOINet.
