Solar Extreme-ultraviolet (EUV) waves are one of the large scale phenomena observed on solar surface often in EUV wavelengths. They are discovered using the data of the EUV Imaging Telescope (EIT) onboard the Solar and Heliospheric Observatory spacecraft (SoHO). This is the reason they are initially named as EIT waves. Later on, they are termed as EUV waves, coronal waves, large coronal propagating fronts, and solar tsunami by different authors. Because of the tight relation between coronal mass ejections (CMEs) and EUV waves, there understanding is crucial for the space weather purpose. In this proposal, we plan to study the EUV wave events occurred during solar cycle 25, which begin in December 2019. In this view, first we will collect the clearly visible EUV wave data set observed by different available telescopes. Afterward these events will be analysed for their dynamical, kinematical , and magnetic topology. For the dynamical property, we plan to explore the source location, propagation, energetic and mode conversion of EUV waves. For kinematics, we will investigate different phases of velocity and acceleration. Further, we plan to relate the EUV waves properties with the Solar Energetic Particles Events (SEPs), which includes high energy protons and electrons. To achieve our scientific objectives, we plan to use various various spacecrafts like: SDO (Solar Dynamics Observatory), STEREO (Solar TErrestrial RElations Observatory), and SOHO/Large Angle and Spectrometric Coronagraph (LASCO). The chromospheric counterpart of the EUV wave will be analysed using the full disk Global Oscillation Network Group (GONG) data sets available around the world without any pauses.
