Calculating expected fringe period of interferometric solar traces, if detected (c/o Mike Otte, SARA): Fringe rate = Baseline / wavelength *angular rotation of earth * cos declination ex: Fringe period…
Latest attempt to record interference spikes using radio interferometer. This time, I used Mike’s AD8302-based receiver, with computer now removed 50cm outside box away from receiver and also 6 point…

He copied latest firmware file (only 3.7MB – NOT all the files) on latest Github Raspberry PI repository and copied to boot folder on Raspberry PI 4B SD card and…
My Milky Way map after 6 months! Ptarmigan Ex-Military Band 3 array. Hydrogen 1420.405MHz Andy Right click link below to download all viable LRO data up to 22/6/2024 (NPZ and…
In order to stop me making the mistake of forgetting to run “Bias-tee-on” each time I restart this computer, I have added a separate 5V power supply to the LNA…
I’m an idiot!! Just had to discard several weeks of data on my Milky Way Hydrogen-mapping experiment (Ptarmigan array) because I stupidly forgot to run the Bias-Tee-On batch file to…
The graphs below show my graphs from these two days – the incredible aurora with the crown visible overhead came from an enormous sunspot group. There are many large SIDs…
The traces below show some SID-monitoring traces at very low frequency radio (23.4KHz) , demonstrating multiple large SIDs around the date of the incredible visible aurora borealis seen throughout the…
