DESCRIPTION:Speakers: Vladislav Lukmanov (Lebedev Physical Institute)\nThe
  results of the analysis of interplanetary scintillation observation data 
 obtained by the radio telescope Big Scanning Antenna of the Lebedev Physic
 al Institute (BSA LPI) before\, during and after the magnetic storm that o
 ccurred on December 1-2\, 2023 are presented. The observational data are c
 ompared with model calculations for corotating and propagating large-scale
  disturbances.  The results of observations of scintillating radio sources
  indicate that the magnetic storm that took place was caused by a superpos
 ition of two types of large-scale solar wind disturbances.  On the day bef
 ore the start of the magnetic storm\, signs of interaction between the Ear
 th's magnetosphere and the corotating region of multi-velocity solar wind 
 flows were observed\, whereas later signs of magnetosphere disturbance by 
 coronal mass ejection spreading after the M9.8 solar flare on November 28\
 , 2023 were observed.\n\nhttps://indico.particle.mephi.ru/event/436/contri
