On International Women’s Day in Buryatia because the sun can worsen television and radio – UlanMedia

Ulan-Ude, March 6, UlanMedia. International Women’s Day on March 8 inhabitants of the Republic of Buryatia expect problems with television and radio broadcasting – the signal can deteriorate due to the interference of the spring. So is the phenomenon when the Sun, the satellite communication and receiving antenna terrestrial repeaters are arranged in a line. Sun – a powerful source of radio, being exactly behind the satellite communications, television and radio jamming terrestrial broadcasters. As explained by the correspondent. IA UlanMedia Head Observatory BSU Lily Mironov , the signal will not disappear completely, but just expected interference.

 

During the spring on television interference may appear subtle interference. According to the news agency Tass, the press service of the Russian Television and Radio Broadcasting Network (RTRS) explained that the RTRS affiliates accept and relay TV signals with different communication satellites. Each of the spacecraft orbit and its different start and end times of interference.

 

The first line between the sun and receiving antennas will begin to cross the satellite “Yamal-202″, and the last of the area of ​​occurrence of interference will satellite “Express-AM44″ – March 17 “.

 

The press service stressed that each region has a schedule of interference. For example, in the Urals and Siberia, March 8 TV picture screens may disappear from 8.40 to 12.45 Moscow time, the Central Federal District – from 11.45 to 12.45 MSK, in the Far East – from 08.22 to 09.08 MSK.

 

“interference occurs during the spring every year. This year, he came in the early-mid-March,” – added in the press-service.

 

According to Lilia Mironova, solar activity for the spring interference is irrelevant.

 

– This is not due to solar activity, and due to the fact that the sun and moon, which broadcasts all programs of television and radio, are arranged in one line, because twice a year in spring and autumn sun near the earth’s equator – said the head of the observatory. – This purely geometric scheme leads to the fact that interference will occur. It does not happen often – the end of February – March, until the day of the vernal equinox, which we have March 21 at dawn, at 6.46, the Sun moves from the southern hemisphere to the north. Spring begins. And the same will be with us in the fall. Just a geostationary satellite is too far away, it is the same speed as the speed of rotation of the earth. Therefore, it is not moving relative to us, why is called geostationary. But to him 40 thousand km. And such geometrical scheme – the Sun, moon and Earth.

 

Lily Mironov added that now the sun safely, flashes and no activity.

 

– Communication radio and television may be interrupted when a powerful solar flare occurred on the sun. And now, since there are no flares, solar activity, too, will only interfere – goose TV screen, the noise on the radio. But that signal completely disappeared – never happened.
