Two new T Tauri stars (TTSs) have been discovered in the neighborhood of the isolated, strong H-alpha emitting, TTS (CTTS) TW Hya (b = 23 deg). The first object is a visual binary star formed by two CTTSs separated by 1.5 arcsec (b = 21 deg). The second object may be a weakly H-alpha emitting TTS (b = 28 deg). The high latitudes of the stars indicate that their distances cannot be very large. All these TTSs have similar radial velocities, suggesting the possibility that they are kinematically related. As the nearest cloud is quite far from this group of stars, star formation in situ must be considered. 20 refs.
