Sun transit in 60 seconds

[Job Geheniau]

Hi fellow amateur astronomers,

Here a 60 second transit.

I just pointed the dish to the cold sky and let it go to ground in 30 seconds and then up again.

You clearly see the cold sky noise, 2 times a sun transit and the ground noise.

Ground noise is about + 5 dB and Sun about + 6 dB what I measured with sdr#.

This graph is from Virgo.

Hi all

 

in order to generate 3D plots of noise sources you can try my program TotalPower ( available from download section of my web site http://i0naa.altervista.org/ ) .

 

Attached is a sun plot generated few days ago with my 5m dish and about 4 minutes of automatic sky mapping.

 

TotalPower uses rtl-sdr as receiver and rotate the antenna working in conjunction with PSTrotator (https://www.qsl.net/yo3dmu/index_Page346.htm ) .

 

More plots are available together with the program

 

TotalPower can also plot the HLine.
