Dear Friends,
One of our kids, Michal Wrochna from XIV Staszic High
School in Warsaw (one of our schools which particpate
in HOU)
has captured image of the Sun in radio waves: http://www.cft.edu.pl/~lech/HOU/radio_sun_1.gif
using very simple equipment: parabollic satellite TV
antena, 60 cm diameter,
LNB converter, Signal detector, such as used by people
coming to install
the
antena on your roof.
It is available for about $50 in Poland.
At x-axis you have arc-minutes, on y-axes signal level.
The observation was made in a drift-scan mode, i.e.
with fixed antenna and
the Earth moving around.
