Resumen:
We present 6 new transits of the system WASP-4. Together with 28 light curves published in the literature, we perform an homogeneous study of its parameters and search for variations in the transit?s central times. The final values agree with those previously reported, except for a slightly lower inclination. Wefind no significant long-term variations in i or Rp /R⋆. The O − C mid-transit times do not show signs of TTVs greater than 54 seconds.
