The LOw-Frequency ARray (LOFAR) is a radio interferometer operating in the frequency range 10 -240 MHz (corresponding to wavelengths of 30 -1.2 m). Important issues of its broad scientific program are the solar and space weather investigations. We are expecting that the LOFAR telescope will bring interesting results in these fields. Three new LOFAR stations were built in Poland in 2015 and have been operating since the beginning of 2016. By including these stations to the ILT (International

... R Telescope), the resolution and sensitivity of the whole interferometer were improved and they are, for 240 MHz, 0.1 arcsec and 9.17 mJy/beam, respectively. Using a single LOFAR station, spectroscopic observations of the Sun can be performed; more stations allow us to obtain solar radio images.
