We study the thermal properties of EUI brightening events by simultaneously observing their responses at different wavelengths using spectral data from the Spectral Imaging of the Coronal Environment (SPICE) and imaging data from EUI. Our results indicate that at least some EUI brightenings barely reach coronal temperatures. STCE Solar Orbiter EUI corona campfires EUV brightenings Teriaca, Luca Aznar Cuadrado, Regina Chitta, L.P.
