| Abstract: | The long-term evolution of solar filaments is closely related to the large-scale solar cycle, with their parameters tracing the solar surface magnetic fields and have been long thought to contribute to the polar fields of the next cycle. In this study, we utilize adaptive intensity thresholding algorithm on the archival carrington maps from Meudon observatory and Mcintosh archive encompassing cycles 16 to 23 to extract polar filaments and their parameters, length and area, to see if polar filaments can be identified as precursors to the succeeding cycle strength. Our study suggests that the polar filament area is a possibly better parameter as a candidate for a precursor to the polar field and hence, the next solar cycle. |
