Notes:
. no corrections for radiant position made to the counts.
. ( - ) means no observations made.
. Auroral activity occurred during the night of Nov 5/6.
. A bit better this month, especially the Leonids. I listened for awhile
after
we got back from visual observing. I put a few images on my web page at
http://www.atm.daldot ca/~andromed/leo.html

Observer: Maurice De Meyere
Location: Deurle, Belgium (3 37' E, 51 00' N)
Frequency: 66.29 MHz since July 2001
Antenna: crossed Yagi (x form), 4 elements, astronomical azimuth 270 deg
(= E), elevation 27 deg.
Antenna amplifier: 25 dB max level 90 dBmuV
Receiver: commercial, Progresson 447A, TESLA (Bratislava)
The receiver was calibrated with a Marconi TF2008 signal
generator. Sensitivity: 5 muV (modulation frequency
1000 Hz, frequency sweep 38 kHz) at (S+N)/N = 20 dB.
SWR of antenna alone at 66.5 MHz: 1.4/1 (good to very good),
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 Ghent University format (Prometeos), and are
available for further analysis. Reduction software for DOS and
Windows available].
Raw counts of reflections with a duration of at least 0.027 s
during one hour interval starting at UT:

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.

The results may not be very reliable yet, as I carried out several tests.
Notwithstanding, the Leonids are clearly visible.

On December 7 I attended a meeting of Astronomy Association of Hubei about
the Leonid observations. Mr.Ouyang communicated his observations made on
Jigong Mountain.
He notices there is a relationship between the duration of reflection and
the activity level of the meteor storm, which makes him to believe that
the duration can be an important observational element.
During the 18h-19h period on 18th Nov, individual reflections couldn't
be distinguished. So maybe the counts was underestimated.

(50 kW) and/or Aitana (60 kW); only one station visible with
Spectrogram FFT software; possible drop in power after
November 15;
distance ~1500 km.
Antenna: 3-elements horizontal Cushcraft 50 MHz Yagi tuned to 55.3 MHz;
geographical azimuth 210 degrees (SW); elevation 0 degrees.
Receiver: Yupiteru MVT-9000 in USB mode; sensitivity 0.5 uV at 12 dB S/N
Observing: 800 Hz audio signal from ear-phone socket was rectified,
digitised and fed into a PC via the parallel computer port.
HP VEE was used to process the digitised signal and to store
10-minutes counts of reflections stronger than 0.22 uV
(-120 dBm). Also for all individual meteors date, time,
duration (dead time) and maximum signal are stored.
Dead-time corrected hourly counts for signals stronger than 0.22 uV

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).
3. AT THE OCCASION OF THE 100TH RMOB
Things changed quite a bit since the Radio Meteor Observation Bulletin
started.
Especially the phrase 'to spread rapidly the (Perseid) results via E-mail' in
the above 'About' is outdated, and will be updated next month.
The comparison at that time was of course with snailmail.
RMOB not only kept alive, but constantly grew, thanks to the spontaneous
contribution of dozens of amateurs worldwide.
In this way, 'history' was written, which is readily available to those who
want to study meteor streams. Of course, RMOB is only a starting point,
and hopefully the detailed observations can still be traced too.
The focus of reporting and presenting observational data has shifted now to
the WWW. Yet a simple text summary such as this one is accessible by everyone
and less volatile than web pages.
To cope with the increasing number of observers, more attention will be paid
to reporting in standard formats. Fortunately, RMOB summaries can be generated
automatically from certain logging software. Observations carried out with
the wide variety of hard- and software on different frequencies remain
welcome.
