Abstract: In 2021, Berghmans et al. reported localised brightenings in the highest resolution quiet Sun images to date, taken by EUI onboard Solar Orbiter on May 30, 2020. By now, EUI has observed many EUV brightenings with exceptionally high cadence (1 s) and pixel scale (100 km). While a handful of such data sets have been studied (Narang et al. 2025, Lim et al. 2025), there is ample room to investigate other EUV brightening data sets and to analyze data sets with different focus or science questions. Using a wavelet-based detection scheme (Narang et al. 2025), we will build a catalog of EUV brightenings, with a maximum of derived properties for each event. A typical 1-hour campaign contains tens to hundreds of thousands events depending on cadence. The catalog will contain properties of EUV brightenings observed in quiet Sun, active regions and coronal holes for more than half a solar cycle. When possible, information from other instruments will be included (AIA, SPICE, PHI, IRIS, …). We believe the catalog will be a valuable resource for researchers to investigate science questions related to EUV brightenings and we will make it publicly available via virtual observatory protocol EPN-TAP, making it FAIR (Findable, Accessible, Interoperable and Re-usable). We are convinced this will contribute to a comprehensive understanding of EUV brightenings and small-scale structures in the corona.
