VLF Radio Detection of SIDs (Very low Frequency detection of Sudden Ionospheric Disturbances)

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

Using UKRAA Sudden Ionospheric Disturbance Monitor (SIDs). (See https://sidstation.loudet.org/ionosphere-en.xhtml for more information on SIDs). 23.4KHz.

I am using one mini-PC for each radio astronomy experiment at LRO = these 2nd hand PCs are cheaply available

SIDs are changes in the ionosphere total power detected when solar flare hits the atmosphere. The power is detected from

I am grateful to the help of Andrew Thomas yesterday for helping me to tune my very low frequency (VLF)
