Determination of 3D Trajectories of Knots in Solar Prominences Using MSDP Data

TL;DR

This paper introduces a novel method for accurately reconstructing the 3D trajectories of prominence knots in solar prominences using ground-based MSDP data, without relying on prior assumptions about their motion.

Contribution

The paper presents a new technique for 3D trajectory reconstruction of prominence knots from single-telescope MSDP observations, eliminating the need for trajectory shape assumptions.

Findings

Successfully reconstructed 3D trajectories of prominence knots.

Demonstrated the method on multiple prominence observations.

Provided detailed 3D motion analysis of solar prominence features.

Abstract

In this paper we present a new method of restoration of the true thee-dimensional trajectories of the prominence knots based on ground-based observations taken with a single telescope, which is equipped with a Multi-Channel Subtractive Double Pass imaging spectrograph. Our method allows to evaluate true three-dimensional trajectories of the prominence knots without any assumptions concerning the shape of the trajectories or dynamics of the motion. The reconstructed trajectories of several knots observed in three prominences are presented.
