The requested radars should run specialized scan modes with a 3 s dwell time (beam patterns described below). All other radars should run a 1-min normalscan (no frequency switching). KOD ch A: 0, 1, 2, 3, 4 (reduced scan) KOD ch B: 2 (camping beam) ADE: 5, 6, 7, 8, 9 with interleaved beam 7 GBR: 9, 10, 11, 12, 13 (reduced scan) STO: 4, 5, 6, 7, 8 (reduced scan) PYK ch A: normal scan PYK ch B: 4, 5, 6 (ESR) and 13, 14, 15 (Tromso) HAN ch A: normal scan HAN ch B: 8, 9, 10 (ESR) and 4, 5, 6 (Tromso) Note B: This is a spacecraft working group request to support the Cluster mission during conjunctions with EISCAT. All radars should run a 1-min normalscan (no frequency switching) during these intervals except LYR on Dec 16 (see Note D) and HAN and PYK, which are requested to run the same scanning sequences as for the ISR World Day campaign (see note A): PYK ch A: normal scan PYK ch B: 4, 5, 6 (ESR) and 13, 14, 15 (Tromso) HAN ch A: normal scan HAN ch B: 8, 9, 10 (ESR) and 4, 5, 6 (Tromso) Note C: This is a spacecraft working group request to support the Cluster mission during conjunctions with the Sondrestrom radar. All radars should run a 1-min normalscan (no frequency switching) during these intervals except GBR and STO, which are requested to run the same reduced scanning sequences as for the ISR World Day campaign (see Note A): GBR: 9, 10, 11, 12, 13 (reduced scan) STO: 4, 5, 6, 7, 8 (reduced scan) Note D: This time covers the 'Flow Channel' Discretionary Time request (Herlingshaw). The only radar covered by this request is LYR. All other radars run their normal Discretionary Time programs.
