Geomagnetic Activity from US Nuclear Test in Nevada on 10/18/23

[Bry]

I was curious if the US Nuclear test conducted this Wednesday at the Nevada Test site left a detectable signature in space weather sensors or is contributing to current geomagnetic activity at the moment?

"The U.S. conducted a high-explosive experiment at a nuclear test site in Nevada hours after Russia revoked a ban on atomic-weapons testing, which Moscow said would put it on par with the United States."

This was Solar Wind speed and density and IMF for Wednesday:

does 1 nuclear test affect the whole planet? i dont think so, maybe only in local territories as generated charged particles ionize the atmosphere(but I may be wrong so I will be very glad if somebody proves if i am)

I think it is extremely unlikely. Obviously we do not have detailed information, but it may not even have been a true nuclear explosion. The Fox News document suggests that they used chemicals and radio-isotopes in an experiment related to detection of underground nuclear explosions.

It seems that some scientists believe that an air-burst nuclear explosion leading to an EMP event can influence geomagnetic activity. https://spaceweatherarchive.com/2021/07/29/nuclear-bombs-can-cause-geomagnetic-storms/#:~:text=First%2C the EMP ionizes a,of heaving%2C lurching geomagnetic storm.
