[Time and details of all individual meteor reflections are stored
on file in the Ghent University format (Prometeos), and are
available for further analysis. Reduction software for DOS and
Windows available].

Location: Astronomical Observatory, Ghent University, Belgium
(ED50 coordinates: 3 42' 32" E, 51 01' 25" N)
Antenna (2x): 4 elements horizontal Yagi, pointed East, elevation 20 deg
Antenna amplifier: 10 dB gain
narrow band resonance lambda/4 antenna filter
Frequency: (1)=66.29 MHz (signal) and (2)=65.3 MHz (interference control)
Receiver (2x): modified commercial FM receiver
Data acquisition: 12 bits PC-based A/D convertor, 250 Hz sampling rate
Interference rejection:
dual setup: receiver (1) tuned at distant transmitter, receiver (2)
tuned at empty frequency. Anti-coincidence measurement rejects
registration of broadbanded spurious signals (lightning, computers,
ignition motors, etc).
Further information:
see WWW page (additional info + observational data)
http://allserv.rug.acdot be/~hdejongh/astro/meteor/meteor.html
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:
. the merging activity of the Arietids and zeta-Perseids can clearly
be seen.
. no trace of the June Bootids, as during most years (1996 and 1998
being the exceptions).

Notes:
. June 11-12: nil counts caused by Gulf of Mexico hurricane?
. June 20: receiver removed from Yagi FM antenna and placed on ½ Dipole
interior antenna, horizontally polarized. Heading was SNW.
The attempt at substituting the Sangean's whip antenna for the
Yagi didn't work out to my satisfaction.

Notes:
. "In" (local) artificial interference.
. "Es" = sporadic E layer mode of reflection.
. This month's Es was very strong and affected the meteor recordings
severely.
. Nil counts on June 9-10th (seems beacon signal of MIYAZAKI University was
interrupted).

Notes:
. - no results
. * suspected interference
. I dismantled my system near the end of May to build a new one...
which didn't perform as well as I'd hoped. It was only recently that I've
put it back the way it was. It works well as is but it is messy and I'd
still like to build a new one.

Notes:
. the scaling seems to be again off (too high), so do not compare to previous
years. When I have time, I will try to get them rescaled.
. non meteoric propagation peaks have been deleted.

2. 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).
