Composite spectrum generated from averaging filament spectra obtained at position angles 62°, 77°, and 283°. The emission features seen at 5057 and 6629 Å are [O III] λ5007 and Hα, respectively, from the high‐velocity system, redshifted by ﹩cz\approx 3000﹩ km s⁻¹ relative to the low‐velocity system.
