Abstract:
Occultations of bright stars by planets provide information on the
state of their atmospheres. An occultation of the bright star 45
Capricornii (HIP 107302) by Jupiter occurred on the night of 3/4
August 2009.
The event was observed at multiple sites in Europe, Africa and South
America and with instruments ranging in aperture from 0.4m to 2.2m.
All observations, except one, were carried out in methane absorption
bands centred at 0.89um and 2.2um to minimise the planetary
contribution to the measured stellar flux. Following the application
of special post-processing techniques, differential photometry was
performed. Nearby bright satellites were used as reference sources.
