We present near-IR J H K photometric data of sample of 58 main-sequence, mainly Vega-type, and pre-main sequence stars. The data were taken during four observation runs in the period May 1998 to January 1999 and form part of a coordinated effort with simultaneous optical spectroscopy and photo-polarimetry. The near-IR colors of the MS stars correspond in most cases tp photospheric colors, although noticealbe reddening is present towards a few objects, and these stars show no brightness variability within the observational errors. On the other hand, the PMS stars show near-IR excesses and variability consistent with previous data.
