Jari, From your Lat/long I assumed a -6 hrs from GMT checking the time you saw the Flare I noted two possibilities. One) would be a flare from Cosmos 1340 which at 23:28:14 Local time? was at AZ 285 EL 61 although I don't recall the direction of travel. Two) Iridium 21 tum passed S to North and was at AZ 290 EL 53 at 23:27:15 a little early. At 23:28:14 it was at 327, 42 near UMa. There were other passes but not within two minutes. Jim
