Abstract: Decayless oscillations are routinely observed with AIA and now also with HRIEUV. Co-observations EUI & AIA detect the same decayless oscillations, confirming that they are of solar origin. Decayless oscillations are different from flare-induced oscillations as they do not dampen during their lifetime and they are independent of flares. In fact the driver is unknown. These oscillations have been interpreted as kink-waves and the ratio between the loop length and the period tends to be in the order of 1 Mm/s, suggestive of the coronal Alfvén speed.
