  1. New data April 2008Optical spectral analysisof Earthlights Science Camp 2007 Hessdalen 17 – 23 September 2007 Assistant Professor Bjørn Gitle Hauge Østfold University College, Norway E-mail: bjorn.g.hauge@hiof.no

  2. I λ Intensity plot Calibration challenge • Calibration of wavelength • λ/pix • Calibration of intensity • Camera & grating transfer function • Distance to object (Radar) • m • Determination of source power • W • Deployment of reference light

  3. Calibration absolutely necessary

  4. Reference light • Power saving, gas bulb, Osram 40W • 12V car battery, capacity 60Ah • Inverter 12V,dc – 220V,ac • 8 trained legs

  5. Reference Light spectrum test Mercury high pressure lamp

  6. Intensity plot ref. light 0006 Well enough, may be good for wavelength calibration…

  7. Reference light FINSÅ 820m ROGNE 900m d = 9400m SKARVAN 974m 40W

  26. 20/9-2007 21:59pic. 0465 Finså Nothing, everything is quiet….

  27. Continuous specter… What is wrong???

  28. BASECAMP Rogne VLF RADAR Data Back lobe BASECAMP FINSÅ Main lobe

  29. Radar data

  30. No recording of magnetic field? Sensitivity of the Aurora fields?

  31. September 2004exposure time 30 sec. Sphere Blue ray Fireball Dublett Sphere, fireball and doublet is stationary….. Only blue ray is moving…..

  32. Electromagnetic Hurricane ?

  33. The mystery • Rapid movement or stationary (N-S track) • No sound (V > 1000 km/t) • Continuous specter (Solid or dense plasma) • No heat (Cold plasma 300K) • Large optical intensity • Gives radar reflections while invisible • No magnetic field, or to low sensitivity • Correlation with aurora………..

  34. Traces of heat / fire? Basecamp Finså 2004

  35. Isolated, remote area!

  36. Fake lights! Molotov Cocktail

  37. Impact area

  38. Heat, burning?

  39. No burning bush….mushrooms! Cold Plasma?

  40. Power failure…. No power failure Metal shielding

  41. Air resistance reduced?Air ionization? • No power failure with old shielded metal case cameras • Power failure with plastic case cameras & mobile phones • Walkie-talkie 5W not affected………?!

  42. Thank you for listening!
