Notes:
. Unknown strong tone appeared April 7, 2017, trying to find solution
as rates dropped. I have no idea what the problem is, if it is
that tone destroying my reception or a problem with the notch filter.
. did not get one reflection at all from the Arietids or Zeta Perseids!!
. no corrections for radiant position made to the counts.
. ( - ) means no observations made.
. Zero (0) is actual number meteors not heard/seen per hour!

Observer: Ivan Sergey
Location: private astronomical observatory close to Molodechno, Belarus
(54 16' N, 26 44 E)
Frequency: 88.58 MHz
Transmitter Location: FM-radio station in Spain, France
Antenna: 5 element Yagi Azimuth 270 deg, elevation 5 deg
Receiver: an automobile radio tape recorder "PIONER", 2 columns "Maxxstro"
for amplification of a signal until Jan 11
TECSUN PL-310ET since Jan 12
Observing method: the signal acts on a sound card computer CPU N2600 (1.6 GHz)
Automatic calculation of the number of signals with the help of
Python-script on the basis of MetAn program data
Data sampling system: calculation of number of signals is carried out at
by visual viewing all kept screenshots.

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 April 1993 in
order to spread 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 April
remain unnoticed visually.
RMOB contains typically: summaries of previous month's 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, links to interesting web sites.
RMOB can be copied freely in unabridged and unmodified form. Extracts should
indicate the source (Radio Meteor Obs Bulletin, month and year).

3. ANNOUNCEMENT
I made two short educational videos to show people what we observe.
One show the transit of the ISS over France: https://youtu.be/mLcl_SqD0ko
And the other shows faint meteor echoes: https://youtu.be/VuBdtMpUXvw
