Comments:


1. IRAS 11332-5011.

2. IRAS 11485-4849. An IRAS low-resolution spectrum of moderate quality exists (Olnon et al., 1986), characterized as a star with a "not too thick" O-rich envelope.

3. IRAS 12460-4800.

4. IRAS 15154-3902. An IRAS low-resolution spectrum of moderate quality exists, characterized as a star with spectral type <=M5.

Remarks:
These new Mira-type variables were found by searching UCAC2 catalogue data (Zacharias et al., 2004) in portions of the southern sky for red (UCmag-Ks>=6) stars. The resulting list was used to create a local web page that queried the ASAS-3 database (Pojmanski, 2002) for lightcurves of stars at those positions. This page was scanned by eye for Mira-type variables. Variables detected were checked in AAVSO VSX and VizieR, and known variables eliminated. Stated positions are from UCAC2.

This research made use of the VizieR catalogue access tool, NASA's Astrophysics Data System, and AAVSO's Variable Star Index (VSX).
