Compared to short-period spectral components --- relative to the cutoff period (5 min)--- long-period components of photospheric motions are more energetic and, therefore, more promising candidates for coronal heating. However, whether the energy from these long-period motions can reach the corona remains uncertain. We present the detection of a 50-min decayless kink oscillation of a coronal loop, along with a corresponding oscillation in the photospheric magnetic field at the loop’s footpoint with the same period. This finding indicates that the 50-min photospheric oscillation excites the coronal oscillation, suggesting that energy of long-period motions is indeed transported up to the corona. The observed transfer of the 50-min photospheric oscillation to the corona highlights the potential of low-frequency power in the photosphere as a significant energy source for sustaining the million-degree temperatures in the corona.
