Abstract: The first significant Forbush decrease of the solar cycle 25 was recorded on November 4th, 2021. The Forbush decrease was observed with numerous ground based cosmic rays stations including Belgrade cosmic rays muons’ station. Series of coronal mass ejections during October 28--November 4 2021. produce conditions for this Forbush decrease. We discuss here the variation of cosmic rays’ flux detected with ground-based detectors and connection with conditions, measured in-situ, in interplanetary space around Earth, flux of solar wind protons measured with SOHO probe to assess implication for solar-terrestrial coupling processes.
