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.
