Measuring data at 102.1 degrees elevation with Ptarmigan Array (Milky Way Hydrogen Map)
Admin
It appears my map with the extra 96.6 degrees elevation readings is now close to maximum I can achieve (see plot on previous post). I am going to try adding…

Results of adding 96.6 degrees elevation (beyond Zeinith by 6.6 degrees) to my galactic hydrogen map
Which muon detector should be on top when there is pair of muon detectors on top of each in coincidence mode (master/slave configuration)?
I have been sent the following answers to the above question: Andy 1. From Dr Spencer N. Axani, of the CosmicWatch project: Hi Andrew, Thanks for the email. It cannot…
Adding bricks to point the Ptarmigan Array beyond the Zenith 21/12/2023
Today I decided to find out what happens when I take the array to point other side of Zenith (ie > 90 degrees). Will it just give same data as…

Working settings for meteor radio scatter detection at LRO during Geminid Meteor Shower 16/12/2023
These settings were very effective, and I should use them in future.

Stack of Mini-PCs at Lichfield Radio Observatory (LRO)
I am using one mini-PC for each radio astronomy experiment at LRO = these 2nd hand PCs are cheaply available on ebay.
Sudden Ionospheric Disturbance (SID) Monitors
SIDs are changes in the ionosphere total power detected when solar flare hits the atmosphere. The power is detected from Very Low Frequency (VLF) radio signals travelling through the ionosphere.…
Major problems with multiplying interferometer
I think I bit off more than I could chew by deciding to build a multiplying interferometer based on AD8302 amplitude phase comparator board from Amazon. I am very grateful…
