Hi All. Been collecting gamma counts at my radio observatory for over a year. A month ago, there was a strange 6X background gradual spike in the gamma radiation observed. Peaked in about half an hour, then tailed off to normal background in another couple hours.

What do you guys do for data analysis? What about comparing data to verify odd events like this one?

I have no idea what this spike could have come from.

A description of the setup is here:
www.typnet.net/AJ4CO/Publications/Gamma%20Field%20Mesurements%20at%20AJ4CO%20Observatory%20-%20DRAFT,%20Typinski%20(2018).pdf

Here are plots of the data in question. The spike occurred on March 2nd, 2019, at around 1830 UTC.

Thanks for any advice!

Hi davetyp? can I ask what geiger counter you're using? This can just be noise from the tube.

The counter I'm using is a CD V-700 model 6B made by Victoreen.

I'd considered the possibility of instrumental noise. The fact that it only happened once for 2 hours out of 12,000 hours of data makes me wonder if it's really instrument noise at work here.

Yes unless this thing can be repeated, looks like it needs some more observation.

A search at Spaceweatherlive.com showed no special spikes in the solar flux.
Another possibility is a visitor that had a recent radiation procedure.
