1. MinII = 10.55 J.

2. MinII = 15.30 J.

3. MinII = 11.20 J.

Remarks:
Using the NASA/IPAC IRSA GATOR data server (http://irsa.ipac.caltech.edu/applications/Gator/) epoch photometry data from the 2MASS Calibration Point Source Working Database (http://www.ipac.caltech.edu/2mass/releases/allsky/doc/seca1_1.html) (Cutri 2004) between Right Ascension 300 degrees through to 100 degrees were examined.

Three candidate variable stars were noted and checked against the CDS SIMBAD and VizieR bibliographic and catalogue services, as well as the proven and candidate variable objects published in the tables of Plavchan et al. (2008). None of them appeared in any of these.

The solutions for these objects are presented here.
