Fig. 5 --- The light curve of a star showing what may be the transit of a giant planet during one night. In the top panel we indicate a 1.5-hour duration in which the star's flux is diminished by 0.014 magnitudes. In the bottom panel, we show the same light curve, this time with individual exposures binned into groups of three so that there is higher signal-to-noise for each data point. The colors of this star are consistent with a G2 main-sequence star, implying that if the event is due to a planetary transit, the planet is roughly 1.2 Jupiter radii in size.
