Overview of the FOV analysed in this article. Left panel: LoS magnetic field (where white is positive polarity and black is negative polarity) saturated at ±100 G as measured by SDO/HMI at around 00:09:41 UT. Middle panel: Same FOV as sampled co-temporally by the HRI_EUV 17.4 nm filter. The red contours in both these panels outline the EUV brightenings detected in this frame using the algorithm described in Sect. 2.2. Right panel: Binary map plotting the locations of all pixels (white) identified to contain an EUV brightening meeting the criteria outlined in Sect. 2.2 in at least one frame within this dataset.
