Radio Meteor Observation Bulletin No. 72                     August 1999


1. FORWARD SCATTER METEOR OBSERVATIONS

Observer:  Enric Fraile Algeciras
Location:  Paseo Bonanova, 8 Barcelona  (02 07'E, 41 24' N)
Frequency: 48.24715 MHz.
Transmitter Location:  still working to identify, possibly South German C2,
           100 kW, horizontal polarisation)
Antenna:   6-element Yagi 617-6B, 14 dBd gain.
           astronomical azimuth 215 deg (=NE), elevation 0 deg.
Antenna:   Six element Yagi 617-6B, 14 dBi gain, horizontal polariz.
           Azimuth 200 deg (NE), elevation 20 deg
Receiver:  home made converter 20 dB gain, 1 dB noise and Kenwood TS-830S.
           10 dB attenuator in the receiver to reduce direct reception
Sensitivity: 0.25 uV for 10 dB S/N
Observing method: the audio signal of the video carrier is received using
           a narrow CW filter (500 Hz) and fed into the PC in real time.
Data sampling system: using a super 14 bits A/D card to PC/XT
           and "Data Capture" software with 1 second/18 sampling interval
           to store all the > 0.5 s reflections.

Note:
. this month I continued to adjust the system to record only the strongest
  overdense reflections, and at the same time to minimise the strong C 4
  TVE1 noise in Barcelona.

           measured with MFJ/259P SWR analyzer (HF-VHF 1.8 MHz to 170 MHz)
           on Sep 28, 1998.
Observing method: automated setup, 150 samples/second, 8 bit resolution.
           [Time and details of all individual meteor reflections are stored
           on file in the University of Ghent format (Prometeos), and are
           available for further analysis. Reduction software for DOS and

   tuned at empty frequency. Anti-coincidence measurement rejects
   registration of broadbanded spurious signals (lightning, computers,
   ignition motors, etc).

Data format:
   results are shown as total reflection time, expressed as
   a percentage. The actual number shows 10 times this value.
   When no figure is shown, the equipment was either out of service,
   or results could have been affected by interference, sporadic-E.

Notes:
 . difficult month, with a lot of interference, which masks even the
   normal morning hour peak activity.


      Pierre De Groote

---------------------------------------------------------------------------
Observer: Werfried Kuneth
Location: Ferndorf, Austria (13 37' E, 46 45' N)
Antenna:  2 element Yagi, direction southeast, no elevation at 1 m height.
Receiver: IC-706 at 53.76065 MHz, CW-R mode, 500 Hz CW filter, fast AGC.
Transmitters: 1) 30 kW TV video carrier from Bari, Italy, distance 700 km,
          direction south and 2) a 30 kW TV video carrier from Sicilia,
          Italy, distance 900 km, south. The total echo power of both
          transmitters is processed into same 40 Hz virtual
          receiver channel.
Observing method: automatic setup using FFTDSP42t software by AF9Y to record
          the audio signal. 20 channels of 2 Hz width are used for meteor
          identification, another channel is used for automatic
          interference rejection. Sampling interval: one 4096
          point FFT every 0.5 seconds.

 The monthly results showing the total reflective time are now also
 available at http://www.qsldot net/oe8fnk this includes now also Es, FAI
 and fireball statistics.

 The meteor counts below are corrected for a full hour observing time. If
 the recording duration is 20-40 minutes, a dot is shown after the value, to
 show the reduced accuracy. Results for less than 20 min. observing time are
 excluded.


       Counts of reflections longer than 6.5 seconds, assumed
       to be overdense.

Notes:
 . an unexpected meteor outburst occurred during daytime on July 2,
   at 7-15h UT. The radiant cannot be determined from the echoes.
   From the known active radiants only the June Bootids have been
   over the horizon.
 . the Pegasids showed up quite well on July 9, while not registered
   in 1997 and 1998.
 . the S. Delta Aquarids showed good activity for several days.
   see also  http://www.qsldot net/oe8fnk for the monthly graphs.
 . every day from July 3 to July 28 showed sporadic-E propagation.

2. ANNOUNCEMENT

Pierre Terrier communicates that METEOR v 3.0 is now available on his
new Web site:

        http://membres.tripod.fr/meteor_astro_elec

The problem remains the treatment of the enormous amount of data collected
by METEOR.
A colleague of his writes a program for the automatic analysis of the
files. Another one prepares a presentation program, similar to the one
of the University of Ghent (colored bar chart).


3. ABOUT THE RMOB

The RMOB is an independent initiative of some workers in the field of radio
meteor scatter observations and data reduction. It started in August 1993 in
order to spread rapidly the Perseid results via E-mail. Since then, it has
appeared monthly, and it has gradually been expanded. In regularly publishing
summaries of observations, potential radio observers are kept up to date of
existing installations, possibilities and limitations of radio meteor
observations. In the long run, there should be sufficient observing stations
to cover the whole globe, allowing to detect stream outbursts which may
remain unnoticed visually.

RMOB contains typically: summaries of recent observations, equipment data,
first results of stream activity by radio methods, relations between radio
and optical meteors, references to other publications in the field of meteor
astronomy and radio scatter techniques, announcements of meetings, short
questions and answers, non-commercial (second hand) sale of radio equipment,
available software.

Contributors are mentioned, and interested persons are asked to contact them
directly.

RMOB can be copied freely in unabridged and unmodified form. Extracts should
indicate the source (Radio Meteor Obs Bulletin, month and year).

If you want to subscribe (or un-subscribe) to the E-mail distribution list,
please send a message to C. Steyaert.
Those not having access to E-mail can obtain a printed copy free of charge
from J. Van Wassenhove (current or back-issues).
