Note. The ut date is the date of the beginning of each night. The cycle number is in periods from the ephemeris given by Agol et al. (2009). For some nights, the exposure time was changed during the observations; this is indicated by the second value in parentheses. The data rms is per exposure for the ratio of intensities of the target and the comparison star. The barycentric mid-transit times of the HD 189733 system are given with uncertainties defined as 68 per cent confidence limits.
