The HST database has been recently significantly completed with :
– raw public observations acquired in support to Juno in 2017-2018, complementing the campaign : Jupiter, Nov. 2016-Sep. 2018 (STIS, 137 images, 12 spectra) ;
– sequenced 100-s long exposures built from a subset of these images ranging Juno perijoves 2 to 12 enabled by the STIS time-tagged mode (NB : specific request of sequencing can be dealt with on demand) ;
– polar projections of this subset of images organized as a function of SIII longitude on top of which was superimposed the Juno magnetic footpath (during the HST exposure) using the most recent (JRM09) magnetic field model and magnetic markers of the footprint of the galilean satellites.

The search interface has been updated so that spectroscopic data can now be sent online to the Cassis software via the SAMP protocol to interactively work with them. To do so, launch the Cassis software first and click on the link "Cassis" available at the bottom of any HST spectroscopic data product.

HST observed Saturn’s northern aurorae throughout 2017, across solstice (reached on 24 May). These observations were carefully coordinated with expected passes of the Cassini spacecraft within the source region of Saturn’s auroral kilometric radiation (found to be colocated at Earth with acceleration regions), i.e. along magnetic field lines mapping to atmospheric aurorae. There are released before the end of the HST proprietary period as an acknowledgement to the support of the Cassini project to this observational campaign :
