Il following system is able to be able to observe  il I transit of radio sorgenti  che they send forth in the continuous one.
During two  annis they have been recorded numerous transits of sources among which  il  Sole, Luna , Radio galaxy
M31 in Andromeda, Galactic Center.
The transits have been observed to the frequency of  
10/12 GHZs in this   banda of frequency particular artificial interferences they are not accused except in the portions of sky in which the television geostationary satellites are positioned.
Knowing therefore such position results possible under conditions stable meteo to effect interesting sessions osservative astronomic radio.
Nevertheless the gang of the
10GHZ results to be very sensitive to the passage of cloudy bodies (Hydro Meteors) that some times hide the observations of the rising radios in transit in the cone radio of the parable.

                                                                                    RADIO OBSERVATION  ECLIPSE TOTAL MOON
                                                                                 March  3 th 2007
                                                                                 Final relationship

                                                                         
 

 

 L'eclisse of Moon particular astronomic event has always been observed using optic tools, but never in gang radio and particularly to the frequency of 11GHZ.
In this portion of frequency it is possible to realize interesting sessions osservative astronomic radio through the use of sensitive Radiometers, tools able to measure the thermal issues sent forth by the celestial bodies in gang radio.
The analysis of the picked data brings further information and details, impossible to optically follow, in virtue of this principle the day March 3 rd 2007 has been realized for the first time a radio observation of the total eclipse of moon to the frequency of 11GHZ.
 L'esperiment was contemplated to the measurement of the variation of temperature of the lunar ground during the whole phase of the eclipse, this phenomenon it provokes on the lunar superfice a notable due thermal start to the cone of shade of the earth.
 La measures you/he/she has been effected realizing some lunar transits in the bundle of a parable first fire from 1.5 mt of diameter, the spar it has an opening of bundle of around 1,2░ equivalent to the total diameter of two placed side by side moons.
The observation is initiated to the hours 21.40 UTCs, after a beginning of evening marked by the worrisome transit of cloudy idrometeore(corpi), in degree to hide the radios observations; in fact the frequency of 11Ghz results to be very sensitive to the atmospheric component.
Realized graphic  Dai is possible to observe a notable variation of temperature  pi¨ accented in the central phase of the eclipse.
 Il primo di grafico di reference to the hours 20.53 UTC represents the beginning of the eclipse with an elevated and constant temperature of the lunar ground for the whole transit.
 Il according to graphic it represents the maximum one some eclipse to the hours 23.20 UTCs with an evident but constant attenuation of the temperature.
The third graph represents the phase of exit of the moon from the totality of eclipse times 00.00 UTCs, the layout it underlines a thermal activity  pi¨ accented in the first halves the graph and more constant in the second part of the same.
Graphic quarter represents the exit of the moon from the totality of the shade, the evanescence of the signal it is motivated from the fast cooling of the lunar ground.
 La final totality of the phenomenon has been observed to the hours 02.09 UTCs the temperature of brillanza of the lunar ground is almost returned to the normalcy as you/he/she can also be noticed by the ampleness of the same signal, even if it still results present in the transit a thermal component not perfectly stable.
The whole phase I Remove osservativa you/he/she has been realized in total absence of phenomenons transitory meteo, in degree to influence the observation instrumental Radio metrics of the phenomenon.
The evolution of the observed phenomenon imposes more deepened studies on the composition of the lunar ground but particularly on the behavior of the same in the microwaves; of notable interest radio observations of the lunar superfice to lower frequencies as the 5GHZ would result.
