We report the internal proper motions of 12 GHz methanol masers in massive star-forming region G35.20-0.74 observed with the Very Long Baseline Array (VLBA) at
Here we briefly present some design approaches for a multifrequency 96-antenna radioheliograph. The configuration of the array antenna, transmission lines and d
CCD photometric observations with B and V passbands were performed on the contact binary V3 in the field of open cluster M37. The solutions were obtained for da
