The Parker spiral’s accuracy is investigated through its prediction for the angle of the interplanetary magnetic field observed by satellites near 1 AU. Simulations were run using simple solar wind parameters and results were compared with measured data from STEREO A and B. Several distribution plots are made to numerically analyze the prediction quality over a six-year period. Investigation was focused on the difference between prediction quality in the ecliptic plane and in three-dimensional space.
This paper is a result of a preliminary analysis on a program written to investigate the Parker spirals. The program, a deployable Python flask application, is a major part of the URS project and is subject to further improvements as this project will continue to be carried on. The next steps will be to analyze solar energetic events using the Parker spiral in conjunction with other instruments. Additionally, this model will be compared with other existing, more complicated models for the interplanetary magnetic field to yield meaningful comparisons for the accuracy in predicting the magnetic field structure.
