ABSTRACT We report the status of the Mexican Array Radio Telescope (MEXART) in preparation for the next solar maximum. During this epoch, the MEXART will be one of the four dedicated radio telescopes (with the ORT in India; STEL in Japan; and MWA in Australia) to track large-scale structures in the solar wind using the interplanetary scintillation (IPS) technique. This network of IPS observatories will produce, for the first time, four g maps of the sky showing the size and shape of disturbances between the Sun and the Earth. We describe the operation and current observations of the first IPS radio sources at 140 MHz detected by the MEXART. These observations use a plane dipole array of 1024 elements (16 lines with 64 dipoles each one), feeding a Butler matrix of 16x16 ports. This system generates 16 lobes at fixed declinations covering 120 (from -40 South to 80 North). The beam fan uses the Earth’s rotation to cover the whole sky. The observations that will be made with the network of observatories of interplanetary scintillation will complement the observations of other observatories, instruments in situ, space probes, satellites, among others." @default.
