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
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
Reference light • Power saving, gas bulb, Osram 40W • 12V car battery, capacity 60Ah • Inverter 12V,dc – 220V,ac • 8 trained legs
Reference Light spectrum test Mercury high pressure lamp
Intensity plot ref. light 0006 Well enough, may be good for wavelength calibration…
Reference light FINSÅ 820m ROGNE 900m d = 9400m SKARVAN 974m 40W

Continuous specter… What is wrong???
BASECAMP Rogne VLF RADAR Data Back lobe BASECAMP FINSÅ Main lobe
No recording of magnetic field? Sensitivity of the Aurora fields?
September 2004exposure time 30 sec. Sphere Blue ray Fireball Dublett Sphere, fireball and doublet is stationary….. Only blue ray is moving…..
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………..
Traces of heat / fire? Basecamp Finså 2004
Fake lights! Molotov Cocktail
No burning bush….mushrooms! Cold Plasma?
Power failure…. No power failure Metal shielding
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………?!
