proximity to the event has not occurred during the cusp crossing, most probably the parameters of the lensing system would be derived more accurately. All the fitted model parameters can be verified by incorporating data from other ground-based telescopes and the EPOXI spacecraft, which also observed the event.

The presence of the planet caused two well-separated anomalies, each lasting a few days. One may ask why more such detections were not claimed before as microlensing surveys had a cadence of one day a decade ago. It should be noted that even though such a cadence should be enough to detect anomalies caused by similar planets in other events, it is not enough to give a high level of confidence. Only recently microlensing surveys achieved cadences of $15-60$ minutes over many square degrees in the Galactic bulge, which allows reliable detections of such planets. Microlensing planetary discoveries benefit most from the follow-up observations only if the central or resonant caustic is causing the anomaly [@griest98] as was the case for OGLE-2005-BLG-071 [@dong09a] and MOA-2011-BLG-387 [@batista11]. In the event analyzed here, the planetary caustic is causing the anomaly in the light curve. In such events, the anomaly is well separated from the
