Super-Earth (radius = 2.7 x R_Earth, mass = 6.5 x M_Earth), discovered by MEarth observing system at Mount Hopkins. I include it in the BTE in spite of its faint V-mag partly bercause it's such an important exoplanet and also because with a long wavelength filter (NIR is best choice, but R-band or z-band will do) it's not so faint because the star is so red.

Basic data

    RA = 17:15:18.9, DE = +04:57:50
    Season = June 13
    V = 14.67, J=9.750, K=8.782 (B-V > 1.5, very red)
    HJDo = 4999.712703 (126) and P = 1.5803925 (117) days (as listed in Schneider's Extrasolar Planets Encyclopaedia, HJDo corrected from earlier value)
    Depth = 17.5 ± 1.5 mmag (NIR-band)
    Length = 0.85 ± 0.10 hr (NIR-band)
    Fp = 0.?? ± 0.??, F2 = 0.?? ± 0.??
    b = 0.354
