Progress in astrometry and orbital modelling of planetary moons in the lastdecade enabled better determinations of their orbits. These studies needaccurate positions spread over extended periods. We present the results of the2014-2015 Brazilian campaign for 40 mutual events from 47 observed light curvesby the Galilean satellites plus one eclipse of Amalthea by Ganymede. We alsoreanalysed and updated results for 25 mutual events observed in the 2009campaign.  All telescopes were equipped with narrow-band filters centred at 889 nm witha width of 15 nm to eliminate the scattered light from Jupiter. The albedos'ratio was determined using images before and after each event. We simulatedimages of moons, umbra, and penumbra in the sky plane, and integrated theirfluxes to compute albedos, simulate light curves and fit them to the observedones using a chi-square fitting procedure. For that, we used the completeversion of the Oren-Nayer reflectance model. The relative satellite positionsmean uncertainty was 11.2 mas ($\sim$35 km) and 10.1 mas ($\sim$31 km) for the2014-2015 and 2009 campaigns respectively. The simulated and observed\textsc{ascii} light curve files are freely available in electronic form at the\textit{Natural Satellites DataBase} (NSDB).  The 40/25 mutual events from our 2014-2015/2009 campaigns represent asignificant contribution of 17%/15% in comparison with the PHEMU campaigns leadby the IMCCE. Besides that, our result for the eclipse of Amalthea is only the4$^{th}$ such measurement ever published after the three ones observed by the2014-2015 international PHEMU campaign. Our results are suitable for neworbital/ephemeris determinations for the Galilean moons and Amalthea.
