Title: A comparison of Solar Prominence data between DOT’s Hα and SDO’s EUV (304Å)
Abstract: Two spectral lines are often used to observe solar prominences: Hα and He II 304Å. For this study, both emission lines captured the same prominence structure but at vastly different temperatures: Hα is visible at ~10,000K while He II 304Å at ~80,000K. The 304Å images, though not matching those of the ground based observations in terms of detail, provides the ability to identify the relatively hotter outer region of a prominence. Analysis of simultaneous images of prominences using the SDO’s Atmospheric Imaging Assembly (AIA) at the He II 304Å and the Dutch Open Telescope (DOT) Hα emission lines reveal both similar and different morphology. When comparing observations from both systems it is important to obtain sufficient congruence in order to determine the prominence properties and structure.
