Latest Milky Way map & associated plots at 1420.405MHz (hydrogen) using Ptarmigan Array at LRO (using data up to 17/8/2024)

Processing and plotting with ezRA suite software (Ted Cline)

Calculating expected fringe period of interferometric solar traces, if detected (c/o Mike Otte, SARA): Fringe rate = Baseline / wavelength

Latest attempt to record interference spikes using radio interferometer. This time, I used Mike’s AD8302-based receiver, with computer now removed

2 x Nooelec 1.4GHz mesh antennae

He copied latest firmware file (only 3.7MB – NOT all the files) on latest Github Raspberry PI repository and copied

In order to stop me making the mistake of forgetting to run “Bias-tee-on” each time I restart this computer, I

I’m an idiot!! Just had to discard several weeks of data on my Milky Way Hydrogen-mapping experiment (Ptarmigan array) because

The graphs below show my graphs from these two days – the incredible aurora with the crown visible overhead came

The traces below show some SID-monitoring traces at very low frequency radio (23.4KHz) , demonstrating multiple large SIDs around the
