Extended Data Fig. 3: Spectra from a single pixel located within the strong flare footpoint in the 23rd March 2024 microflare.
From: Spatial variation of energy transport mechanisms within solar flare ribbons
The top row is Lyβ, and the bottom shows Lyγ and Fe XVIII. In all panels, the grey curve is a profile from the pre-flare (23:42:24 UT). Intensity doubles within one 5.1 s snapshot, and peaks around 15 s later. The vertical lines show the wavelength range used for the integration when calculating Rβγ. Note that the intensity scale changes from panel to panel. Error bars on intensity represent combined uncertainties [35] on the SPICE data due to photon shot noise, dark currents, and readout noise. A -50” offset has been applied to SPICE’s solar-Y pointing information quoted on each panel.
