Thursday 28th June 2018 7:30pm-9pm - First Radio Jove Observing Run!

FIRST RADIO JOVE OBSERVING RUN!  Thursday 28th June 7:30pm-9pm.

The predictions for the most easily detectable (and allegedly most reliable) Jupiter radio emissions called "Io B" are for the evening of 28th June and so we will be trying the Radio Jove receivers for real.  This run also overlaps with forecast "C" emissions.   The window of opportunity runs from around 7:30pm our time through to 9pm and so we'll meet from around 7pm to get set up and (hopefully) recording for then.

This is a bit of a milestone for RAG, our first attempt to do observations!

Sunday 10th June 2018 - Radio Astronomy Group Meeting

Hi MBO folks interested in radio astronomy!

NEXT MEETING: 10am 10th June at MBO.

The MBO Radio Astronomy Group (RAG) met on Sunday 13th May and worked  on trying to understand more about the 21cm receiver equipment we have and how exactly it works, and also to work on the radio jove project.

With the 21cm equipment we looked at the circuit diagrams and how the output from the receiver we have been using appears to come out before the interferometer stage.  The exact functioning of the interferometer stage itself is unclear, it does not appear to be tunable and so how it adapts to the red-shift of galactic sources is unclear. It has two outputs, a signal level and a phase angle.

With the radio jove project we now have two separate Jupiter emission software packages, one being the software for Windows that the Radio Jove people at NASA recommend and a more useful cross-platform script written in Python which, after reporting a bug with, produces results which correlate with the Windows package.

We also now have a better understanding of the emissions from Jupiter itself, there are at least 7 different types and it is one particular type associated with the moon Io which has the strongest signal.  The
condition of the Earths atmosphere also plays a large part in how easy it is to receive these signals.

It is also apparent that we need to do continuous monitoring of these signals to have a chance to detecting them, it is not enough to just turn it on and listen "just in case".  So we will need to acquire a USB audio interface for the Raspberry Pi 3 to fulfill this function.

Finally we have a new project to work on, we want to build and install magnetometers at MBO!  This is to monitor changes to the Earths magnetic field in response to geomagnetic storms.  It should also detect cars arriving and leaving, but they will have a very different type of signal.

Look forward to seeing people at the next meeting on 10th June!

All the best,
Chris

Sunday 13th May 2018 - Radio Astronomy Group Meeting

The next scheduled Radio Astronomy Group (RAG) meeting will be 10am Sunday 13th May at MBO.

Things to work on are:

  • If the weather is good we will focus the second 21cm dish
  • Investigate oddities about the 21cm receiver
  • Try and understand the types of radio emission from Jupiter
  • Get predictions for Jupiter's radio emissions to allow observations

See you then!

Please note: MBO will always be closed on days of Severe, Extreme and Code Red fire ratings, please see the CFA website for up-to-date information.

Sunday 6th May 2018 - Radio Astronomy Group "Extra" Meeting

Hi radio astro folks,

Sunday 8th April we made good progress learning how to focus the 21cm dishes and were able to get one done by the time we had to finish early.  The next meeting will be the "extra" meeting at 10am Sunday 6th May.

If we have enough people we will work to finish focusing up the second dish and if not we will investigate oddities about the 21cm receiver. We can also do more work on the Radio Jove equipment, mostly working out how to do the predictions necessary for observing the various types of radio emission from Jupiter.
