The APIS service relies on a database of spectro-imaging auroral observations of the outer planets and their moons acquired by the Hubble Space Telescope. Various data levels can be browsed with the Search Interface through conditional search criteria.


Jupiter monitoring in support to Juno

21 Jul 2017

Raw HST observations of Jupiter, corresponding to the Juno cruise phase and early orbits, are now browsable :
- Jupiter, May.-Jul. 2016 (STIS, 45 images, 3 spectra)
- Jupiter, Nov. 2016-Jul. 2017 (STIS, 121 images, 9 spectra)

Early release of Saturn’s pre F-ring observations

08 Jun 2017

Since summer 2016, observations of northern Saturn’s aurorae are obtained on a regular basis in coordination with Cassini polar passes within the auroral regions. The observations matching Cassini pre F-ring orbits are released today before the end of the HST proprietary period as an acknowledgement to the support of the Cassini project to this observational campaign :
- Saturn, Jun.-Aug. 2016 (STIS, 6 images)

Spring update

21 Mar 2017

New observational campaign :
- Europa, Feb. 2014-Apr. 2015 (STIS, 59 spectra)

Update of plots of Saturn’s polar projections :
- For the 2016 and 2017 observations associated with the Cassini ’Grand Finale’, polar projections will draw the footprint of the Cassini trajectory (red = HST exposure, gray = +/-2h wrt HST exposure).
