Summary of the used CRISP observations for the present analysis.

	Hα 6562.81 Å	Ca II 8542 Å
Date of observations	June 7, 2014
Observing intervals	07:32 UT–08:21 UT and 08:28 UT–09:16 UT^(a)
Wavelengths	Hα LC, ±0.26 Å, ±0.77 Å, ±1.03 Å	Ca II LC, ±0.055 Å, ±0.11 Å, ±0.495 Å
Temporal cadence	4 s	4 s
Pixel size	0.059″	0.0576″

Notes. We note that as in Paper II, no UV, EUV Atmospheric Imaging Assembly (AIA; Lemen et al. 2012) and Helioseismic and Magnetic Imager (HMI; Scherrer et al. 2012) magnetic field observations are used due to their low spatial and temporal resolution compared to CRISP observations.

^(a)

There is only a small temporal offset of ∼2 s between the Ca II and Hα time series as the two lines were observed sequentially. Only the second 48-min observing interval has been used in the present analysis.
