For 4 of 5 recently proposed members, signatures of youth such as Li\\,I 6708 \\AA\\, absorption and H$\\alpha$ emission further strengthen the case for youth and membership. Effective temperatures are determined via line ratio analyses for the 11 F, G and early K stars observed, and via spectral comparisons for the 8 late-K and M stars observed.
