Abstract
We studied intensity oscillations of the coronal green line ([Fe xiv] 530.3 nm) observed with two coronagraphs at Lomnický Štít and Norikura nearly simultaneously. In the spectroscopic data obtained at Norikura, we have detected and confirmed the earlier detection of 5-minute oscillations in photoelectric photometer observations made at Lomnický Štít. Quasi-periodic structures in the green-line intensity with a tangential speed up to 400 km s−1 have been detected for the first time. We briefly discuss the implications of these oscillations on the coronal heating mechanisms.
