We report the detection of 6 active galactic nuclei, and also the marginal detection of the galactic center radio source SgrA*, in 215GHz VLBI observations between the IRAM 30m telescope on Pico Veleta and one 15m antenna of the IRAM Plateau de Bure interferometer (~0.3mas fringe spacing). In this (second) 1.4mm VLBI-experiment we find source dependent ratios between the total and correlated flux densities in the range of 10-35%, indicating partly resolved brightness distributions on sub-milliarcsecond scales. In view of the calibration uncertainties and the limited uv-coverage at this high frequency this needs further confirmation. The present detection limit of ~0.4-0.5Jy opens the possibility for more extended 1.4mm VLBI experiments, in particular with phased millimeter arrays.
