AI Thread Summary
A geomagnetic storm is a temporary disturbance of Earth's magnetosphere caused by solar activity, specifically when solar wind interacts with Earth's magnetic field. This phenomenon is a significant aspect of space weather and can lead to effects such as the aurora borealis. The recent discussion referenced a geomagnetic storm linked to a coronal mass ejection that occurred on January 24. It's important to clarify that geomagnetic storms are caused by solar activity, not the other way around. Understanding these storms is crucial for comprehending their impact on Earth and space weather.

can somebody explain to me what is geomagnetic that recently run down to earth?
i really want to know.
 
Astronomy news on Phys.org
I'm sorry, what are you referring to? I've never heard of a geomagnetic.
 
i'm really sorry if i got it wrong. but, i just want to know about something at the space that fall to earth, and produce solar storm.i don't really know what it is.
 
Maybe he is referring to the geomagnetic storm that was caused by a solar coronal mass ejection and caused the aurora borealis on January 24?
 
Here is an excerpt from an article that explains it in detail.

Geomagnetic storm
A geomagnetic storm is a temporary disturbance of the Earth's magnetosphere caused by a disturbance in the interplanetary medium. A geomagnetic storm is a major component of space weather and provides the input for many other components of space weather. A geomagnetic storm is caused by a solar wind shock wave and/or cloud of magnetic field which interacts with the Earth's magnetic field.

Timacho, please note that the geomagnetic storm does not produce a solar storm. Quite the opposite. The geomagnetic storm itself is caused by solar activity. It is
called "geomagnetic" [geo=earth] because it is triggered when the solar wind interacts with Earth's magnetic field.

Thread 'How feasible is home radio astronomy?'

Is a homemade radio telescope realistic? There seems to be a confluence of multiple technologies that makes the situation better than when I was a wee lad: software-defined radio (SDR), the easy availability of satellite dishes, surveillance drives, and fast CPUs. Let's take a step back - it is trivial to see the sun in radio. An old analog TV, a set of "rabbit ears" antenna, and you're good to go. Point the antenna at the sun (i.e. the ears are perpendicular to it) and there is...

Thread '3I/ATLAS, Interstellar Comet'

3I/ATLAS, also known as C/2025 N1 (ATLAS) and formerly designated as A11pl3Z, is an iinterstellar comet. It was discovered by the Asteroid Terrestrial-impact Last Alert System (ATLAS) station at Río Hurtado, Chile on 1 July 2025. Note: it was mentioned (as A11pl3Z) by DaveE in a new member's introductory thread. https://www.physicsforums.com/threads/brian-cox-lead-me-here.1081670/post-7274146 https://earthsky.org/space/new-interstellar-object-candidate-heading-toward-the-sun-a11pl3z/ One...
