Photometry and spin rates of 4 NEAs recently observed by the Mexican Asteroid Photometry Campaign

We present photometric observations of (4055) Magellan, (143404) 2003 BD44, 2014 JO25 and (3122) Florence, four potentially hazardous Near Earth Asteroids (NEAs). The data were taken near their approaches to Earth by 3 observatories participating in the Mexican Asteroid Photometry Campaign (CMFA). The results obtained: light curves, spin rates, amplitudes and errors, are in general agreement with those obtained by others. During the day of a NEAs maximum approach to our planet, its light curve may present significant changes. In the spin rate, however, only minute changes are observed. 2014 JO25 is briefly discussed in this regard.
