>1. FORWARD SCATTER METEOR OBSERVATIONS
>
>Observer:  Enric Fraile Algeciras
>Location:  Barcelona, Spain (01 59' E, 41 21' N)
>Frequency: 48.250 MHz
>Transmitter location: most likely Czech television C2 C. Budejovica,
>           100 kW, horizontal polarisation.
>Antenna:   6-element Yagi 617-6B, 14 dBd gain.
>           astronomical azimuth 215 deg (=NE), elevation 0 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 (100 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 9 second/18 sampling interval to
>           store all the > 1.0 s signal increases.

>Antenna (2x): 4 elements horizontal Yagi, pointed East, elevation= 20 deg
>Antenna amplifier: 10 dB gain
>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).

>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.

>2. ANNOUNCEMENT
>
>Another outburst?
>
>The (meteorobs) mailing list (subscription instructions, see:
>http://www.tiacdot net/users/lewkaren/meteorobs/subscribe.html) carried a
>visual observation report from John Holtz (east coast of the USA) of
>a meteor outburst between July 18, 1h50 UT and 2h15 UT, with rates between
>1 and 2 per minute. "The meteors may have been concentrated around
>the Big Dipper, Draco, Bootes, and Hercules area. All of them were heading
>due south, so we couldn't determine a likely radiant."
>
>This outburst shows in the radio observations of Enric Fraile Algeciras,
>the University of Ghent, and Maurice De Meyere (detailed report next month),
>but not in those of Werfried Kuneth. Probably this can be explained by the
>difference in geometry, the former stations receiver-transmitter direction
>being roughly west-east, but Werfried's direction being south.
>This can be an indication for a radiant low in northern direction observed
>from Europe.
>Also on (meteorobs) Jin Zhu <zj@bac.pkudot edu.cn> mentioned the radiant
>associated with near-earth-asteroid 1997 BR, with maximum rate around
>July 19 and theoretical radiant near R. Asc 175 deg, Decl +65 deg (Epoch 2000),
>and atmospheric velocity of 16 km/s (calculation Rob McNaught).
>This radiant could fit the mentioned visual and radio observations.
>

>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).
