[vsnet-newvar 1746] MisV1147 H-Alpha Photometry

[DWest61506@aol.com]

On 12/15/2002 00:50 UT I measured the H-alpha magnitude of MisV1147.  The details of the system and other observations are given below.  My measurements gave a H-Alpha magnitude of 1.74 +/- 0.05.  H Alpha emission is present when the H Alpha magnitude is less than 1.90.  Non-emission stars typically have an H Alpha magnitude between 2.0 and 2.2.  Therefore, MisV1147 does weak exhibit H-Alpha emission. This observation is consistent with the idea that MisV1147 is a YSO.
