A solar wind speed above 500 km/s is considered high and can significantly impact Earth's magnetosphere, potentially causing geomagnetic storms.
A density reading above 10 cm³ is considered high and can impact the Earth's magnetosphere, potentially causing geomagnetic disturbances.

Bz (nT): This is the vertical component of the interplanetary magnetic field. Changes in Bz can indicate solar storms affecting Earth's magnetic field.
Phi (gsm): This measures the angle of the magnetic field in the solar wind. It helps understand the direction of the magnetic field.
Proton Density (p/cm³): This shows the number of protons in a cubic centimeter of solar wind. High density can signal increased solar activity.
Proton Speed (km/s): This measures the speed of the solar wind protons. Faster speeds can mean stronger solar wind impacting Earth.
Proton Temperature (K): This indicates the temperature of the solar wind protons. Higher temperatures are associated with more active solar regions.

Solar Activity: Output remains somewhat elevated. Currently, solar wind speeds are elevated, with ongoing solar activity leading to moderate chances of M-class flares. These flares could result in occasional radio blackouts affecting high-frequency communications, especially on the sunlit side of the Earth.
Geomagnetic Activity and Auroras: A Kp index of around 4-5 is forecast today, indicating the possibility of G1 (minor) geomagnetic storms. However, geomagnetic conditions are likely to fluctuate, leading to auroral activity visible at high latitudes, including northern U.S. states and regions like Canada and Scandinavia. Aurora visibility could extend to more southern regions if geomagnetic activity intensifies unexpectedly. A coronal hole's solar wind stream may impact Earth between October 18 and 19, leading to slightly elevated geomagnetic activity.
