Recognition of the solar activity manifestation in the interplanetary space at joint data analysis from SWA-PAS and MAG instruments of the Solar Orbiter mission.

The shock waves, spatial regions with magnetic field perturbations and irregularities, and other phenomena characterizing the environment in the heliosphere can occur during enhanced solar activity. Clarifying the reasons for these events allows us to better understand the interconnection between processes on the Sun and interplanetary space.

In our study, which is based on the data processing from both SWA-PAS and MAG instruments we examine variations of the different parameters of the solar wind and interplanetary magnetic field derived as a result of in-situ measurements aboard the Solar Orbiter in the first half of 2023.

In the period selected both instruments detected the events with significant variations of the key parameters of the solar wind befriended by specific changes in the magnetic field components. We demonstrate the most outstanding examples of the SWA-PAS and MAG data analysis allowing the identification of the ICME, shock waves, CIR, magnetic clouds, magnetic flux ropes, magnetic holes, and other Heliospheric phenomena with confidence. The particular interest is in the selected simultaneous or serial registration events of the two or more mentioned phenomena presented.
