On November 21, 2003 an ionosphere heating experiment was conducted in Tromsø to investigate the optical effects caused by powerful HF pumping of the ionosphere. During the time interval 18:32 - 18:36 UT, when the heating beam illuminated a region of an upward field-aligned current, sudden appearance of an auroral arc was observed by the ALIS cameras. Strong temporal variations of the intensity of the arc were coincident with the HF pumping modulation period. Analysis of the optical data and the ionospheric parameters measured by the UHF ESCAT radar show that the observed auroral arc was triggered by Alfvén waves exited by modulated HF heating of ionosphere.
