August 2018 - Radio Astronomy Group Meetings

Next "extra" meeting:  Sunday 5th August 10am

An idea we are trying where a few of us who can spare a little extra time try to consolidate some of the work done in the previous "usual" meeting and test out some ideas or equipment for the next "usual" meeting.

We'll be double checking the upcoming Io observation times too.

Next "usual" meeting: Sunday 12th August 10am

Continuing work on the magnetometer project and see if we can graph some data! Also (if the weather is good) try and focus the 2nd dish.

Next Radio Jove "Io-B" Observing: Saturday 18th August 17:30 (sunset) - 19:30


Current status:

The Radio Astronomy Group currently has three projects on the boil at the moment covering the inner solar system with the magnetometer, the outer solar system with our Radio Jove equipment and the galaxy (and beyond!) with our 21cm hydrogen line system.

  1. Magnetometer:   we are currently building a portable 2-axis magnetometer for educational and demonstration purposes with the intention of then graduating to building a full 3-axis magnetometer for permanent installation at MBO (which will need burying underground for a number of reasons).  The idea is to be able to record and graph the local magnetic field of the Earth and to monitor its disturbance by emissions from the Sun that can trigger aurora.
  2. Radio Jove:  We have a pair of Radio Jove receivers (one of which starred on StarGazing Live thanks to the good offices of Lindsay) connected to long dipole antennas on the roof of the log cabin.  Here we are trying to listen to the radio emissions from natural processes on Jupiter.   The difficulty here is that there are only certain times of the week when the geometry of the system coincides with our night time and the next opportunity for observing isn't until August now.
  3. 1410MHz Phase Switched Interferometer:  We have a pair of large dishes mounted above the log cabin which are connected to a phase shifted interferometer.  All of this equipment is on long term loan to MBO thanks to the good offices of Ray.  The receiver itself was custom built by Hans Michlmayr and we are now in contact with him in Western Australia and he has been most gracious in helping us with our misunderstandings about what the system actually is (we had heard it was a 21cm hydrogen line receiver), how it works and what it is intended for.

If any of these projects interest you please feel free to visit, and you'd be most welcome to join the RAG mailing list too!
