The Czech DTH platform Nova Digi CZ has warned of upcoming sun interference in the reception of its DVB-S/S2 service.
In a statement, it says the phenomenon is reflected in reduced quality and the cut-off of the service for a short time.
It adds that the interference is expected to begin at the end of the next working week, around February 26, and to continue during the course of the following week.
Although Nová Digi CZ provides details of when the interference is likely to hit Prague, it also says it will be similar throughout the Czech Republic.
The service is distributed by Intelsat 10-02 at 0.996 degrees West.
According to Intelsat, geostationary satellites are located at around 22,300 miles (36,000km) over the equator. As the equator is offset by 22.5 degrees, the sun aligns directly with satellites and receiving earth stations twice a year, once in the spring and once in the autumn.
During this event, which is known as a sun outage, fade or transit, earth stations cannot distinguish between the energy from the sun and its intended communication signal.
Peak outage time occurs when the sun, satellite and earth station are exactly aligned with each other.
