Daily EUV images featuring the coronal hole. The consecutive panels show EUV images that highlight the evolution of the coronal hole between April 24 and May 5, 2021. The images were prepared by merging STEREO-A/EUVI 195 Å and SDO/AIA 193 Å filtergrams in 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.
