ABSTRACT We request 21 orbits of HST observations to confirm the transit of a candidate Earth analog exoplanet recently detected in the Kepler data set. The candidate Earth-sized (R_p = 1.1 +/- 0.1 R_e) planet orbits its Sun-like (0.97 R_sun) host star in a 365.4 day period, and if confirmed, would be the first true Earth analog around a Sun-like star known. Though our vetting finds no indication that the candidate signal is a false positive, we cannot completely rule out an instrumental origin for the signal without independent confirmation from HST. These HST observations are urgently needed to inform the 2020 Decadal Survey of occurrence rate of Earth analogs around Sun-like stars, a crucial design input for the proposed LUVOIR and HabEX flagship missions.

OBSERVING DESCRIPTION We will observe our target for 21 consecutive HST orbits using the WFC3 instrument. We will begin the observations with a direct image with the F130N filter and then obtain time series spectroscopy with the G141 grism using the NSAMP = 6, SPARS25 readout pattern. We wil alternate forward and reverse scanning on the detector with a scan rate of 0.02 arcsec/sec.

The observations must be centered on the time of transit.
