Daily images of the evolution of the coronal hole from April 24, 2021, to May 5, 2021. The images show merged STEREO-A/EUVI 195 Å and SDO/AIA 193 Å filtergrams as prepared by the CHMAP pipeline. The coronal hole is shown in the heliographic Carrington frame on a 10° grid (white guidelines) from −50° to −10° latitude and 120°–160° longitude. In each image the locations of short-term EUV brightenings that occurred in the time period of ±12 h around the shown frame are labeled “x”. The labeled locations are color-coded according to the time of detection.
