Description
Solar pores unlike Sunspots are difficult to analyse, due to being much smaller in size, the absence of a penumbra and its shape evolution appearing more unstable, giving no fixed boundary of the pore. By using shape analysis tool Deformetrica created by Bone et al (2018), we can fix grid points over the shape of the pore and track the changes as it evolves over time. By doing this, we can extract the horizontal velocity profile of the pore, which we can use for various different analysis, such as combining with magnetic field and line of sight(los) velocity of the same dataset around the pore to derive the poynting flux, or potentially applying Proper Orthogonal Decomposition(POD) to verify any oscillatory behaviour.
