[1] The EISCAT low-gain HF facility has been used 8 repeatedly to produce artificially stimulated optical 9 emissions in the F-layer ionosphere over northern 10 Scandinavia. On 12 November 2001, the high-gain HF 11 facility was used for the first time. The pump beam zenith 12 angle was moved in 3°st...
