Sensitive upper limits to the 2.7 mm fluxes around two T Tauri stars in the nearest molecular cloud L1457 (=MBM 12) are reported. The observations were made with the Berkeley-Illinois-Maryland interferometer, operating in continuum mode. For the sources IRAS F02553+2018 and LkH alpha 264, the 3 sigma sensitivities of the observations were 0.011 and 0.015 Jy, respectively. The present observations are insufficient to constrain the disk masses of these objects because there are more disk model parameters than available data points. However, models using "typical" disk parameters result in disk masses of 0.002 to 0.005 M&sun; and are consistent with the observations. The results indicate that the previously unclassified source F02553+2018 is a weak-line T Tauri star.
