Sec.  2.107  Radio astronomy station notification.



    (a) Pursuant to No. 1492 of Article 13 and Section F of Appendix 3 

to the international Radio Regulations (Geneva, 1982), operators of 

radio astronomy stations desiring international recognition of their use 

of specific radio astronomy frequencies or bands of frequencies for 

reception, should file the following information with the Commission for 

inclusion in the Master International Frequency Register:

    (1) The center of the frequency band observed, in kilohertz up to 

28,000 kHz inclusive, in megahertz above 28,000 kHz to 10,500 MHz 

inclusive and in gigahertz above 10,500 MHz.

    (2) The date (actual or foreseen, as appropriate) when reception of 

the frequency band begins.

    (3) The name and location of the station, including geographical 

coordinates in degrees and minutes.

    (4) The width of the frequency band (in kHz) observed by the 

station.

    (5) The antenna type and dimensions, effective area and angular 

coverage in azimuth and elevation.

    (6) The regular hours of reception (in UTC) of the observed 

frequency.

    (7) The overall receiving system noise temperature (in kelvins) 

referred to the output of the receiving antenna.

    (8) The class of observations to be taken. Class A observations are 

those in which the sensitivity of the equipment is not a primary factor. 

Class B observations are those of such a nature that they can be made 

only with advanced low-noise receivers using the best techniques.

    (9) The name and mailing address of the operator.

    (b) The permanent discontinuance of observations, or any change to 

the information above, should also be filed with the Commission.

    (c) Observations being conducted on frequencies or frequency bands 

not allocated to the radio astronomy service should be reported as in 

paragraph (a) of this section for information purposes. Information in 

this category will not be submitted for entry in the Master 

International Frequency Register and protection from interference will 

not be afforded such operations by stations in other services.
