Campfire (supplement S3 movies, label 63, available online) was observed by both HRI_EUV (position: x  =  737, y  =  1539 in Fig. 4) and AIA (two latest sub-image at final stage). Its duration was more than 245 s in the EUI (14:54:00–14:58:05 UTC) observations. The actual duration in the range of 293 s–312 s was observed in AIA images. The difference in light travel time of 220 s needs to be considered between the two spacecraft.
