Radio Astronomy

The Society is currently starting to investigate the possibilities of radio astronomy and making its first forays into observing at radio wavelengths.  We have acquired an ICOM R-7000 radio receiver that is capable of tuning into frequencies from around 500 KHz right up to 2 GHz.

We have a dual dipole antenna (the “Washing Line”) set up next to the club house which is designed to listen into radio waves generated by the motion of the moon Io as it ploughs its way through the magnetic field of Jupiter.  The radio waves cover a wide range from below 10 MHz to way beyond 30 MHz, but are particularly strong at 20 MHz which the antenna is tuned for.  During the day time the antenna array can also be used to monitor solar activity to detect solar flares which are also strong at this frequency.

A lot of work still needs to be carried out and we are always looking for people with an interest in radios or electronics to lend a hand.  Several members of the Norfolk Amateur Radio Club have been providing us with some expertise in this area.

Public Events

We hold a number of special public events with talks, tour, and look through our telescopes!
