Subject: NZ Daylight Bolide July 7 1999
Urgently request you notify DoD to capture possible imagry/data on above
ent, according to following parameters...
LAT 39.1 SOUTH LONG 174.2 EAST RADIUS 300km ( to capture enture
ground track)
DATE 7 July 1999 TIME 4h 15m UTC +/- 10 minutes
Using some 8 data sets, I calculate (using procedures similar to H.H.
Nininger ~1925) the following Hypocentre/endpoint parameters
(preliminary only.... require larger geo-baseline to refine data)....
HYPOCENTRE (1st calculation) h=28.5km +/- 2.3
(2nd " ) h=29.9km +/- 2.4
centered on geographic co-ordinates 39.1 S; 174.2 E, qith foloowing
error-bars...
+/- 5m in X AXIS, +/- 10km in Y AXIS, and +/- 2.5 km in Z AXIS.
Hypocentre/Enpoint appears to be almost directly over township of
INGLEWOOD, some 40km N of HAWERA, and some 20-25 KM NE of Summit of
famous NZ conical volcano:- Mt Egmont/Taranaki (8,260 feet). Regret
unable to recommend release of SR71 from Moffet Field, due to
obstrcution and misinformation by national media authorities.... could
not establkish possible stratospheriv aerosols until the 15hr "window of
opportunity had elapsed, and frontal/rain weather was imminent. Still
trying to establish start of ground track and suitable intermediate data
points to refine trajectory parameters.
All NZ radio stations willfully destroyed all public observations that
were faxed to them depsite several formal pleas and impassioned on-air"
requests to forward to myself. Tabloid behaviour viz... NOSTRADAMUS,
AREA-51, MULDER&SCULLY etc was almost intolerable. Promised public data
fromAuckland Observatory still awaited.
Confidence of endpoint is high, since own observation and that of a
mariner (using a sextant at anothert location, plus a sonic delay timing
within ~ 20m of ground zero, fixes altitide and azimuth at both our
sites to +/- a single degree!
Definite seismic recording by an alleged 9 stations throughout NZ of
accoustic shock-wave, suggest a possible successful 3-dimensional
triangulation by Govt scientists within next 3 - days (I HOPE!).
Attempts to contact Jack Baggaley at Birdlings Flat, Duncan Steel at
Jindalee, and Robv McNaught at Siding Springs... all unsucessful.
Meteor defintely too far NORTH for Jack and too far EAST for Duncan.
Hear explosion and mapped smoke-ball, but did not see actual visual
passage, as looking in wrong direction, whilst walking to local shops...
sorry, no photos thgis time either!
Will keep you posted of any updates... REPLIES PLEASE TO ABOVE E-MAIL
ADDRESS.
Kind regards as always,
