NEW SUNSPOT. “Unprecedented' high-res image of sunspot captured by new solar telescope. Over the course of a solar cycle, the sun will transition from a calm period to one that is very intense and active. This activity is tracked by counting sunspots on the sun and how many are visible over time. During the peak of this activity, the sun's magnetic poles flip. Then, the sun will grow quiet again during a solar minimum.” https://lnkd.in/dFPrJaV View in LinkedIn

DRIVERS OF SOLAR WEATHER. “The types of space weather phenomena at the different planets depend critically on the magnitude of the intrinsic magnetic field, on the existence and characteristics of the planetary atmosphere and ionosphere, and on the distance from the Sun determining the properties of the driving solar wind and IMF.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

EARTH’S MAGNETISM. “The intrinsic geomagnetic field of the Earth has an intensity of about 50,000 nT in the polar regions and about 30,000 nT at the equator.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

STRUCTURE OF MAG FIELD. “The size of the magnetospheric cavity is determined by the magnetic pressure of the internal field on one hand, and on the solar wind dynamic pressure on the other: The magnetospheric boundary, the magnetopause, forms at a location where the solar wind and magnetospheric plasmas and magnetic fields are in pressure balance.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

MAG FIELD DEFORMATION. “Typical solar wind conditions give a standoff distance of the magnetopause at about 10 RE (Earth radius = 6370 km) upstream of the Earth, but under strong solar wind driving the magnetopause can be pushed well inside the geostationary orbit (at 6.6 RE where a satellite orbiting around the Earth has a 24-hour rotation period and thus remains at a constant longitude above the Earth).” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

DEFORMED SHAPE. “In the antisunward direction, the solar wind flow deforms the dipolar magnetic field to a cometary taillike shape where the magnetopause is on average about 30 RE from the Sun-Earth line, depending on the solar wind pressure. The magnetotail extends far beyond lunar orbit at least a few hundred RE in the antisunward direction.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

POST-ENLIGHTENMENT. “The purpose of this article is to show the shift in emphasis in modern concepts from anthropocentricity and rationalism to bio-, eco-, post-humanism and irrationalism in the digital era. The project known as “Enlightenment” is over. What is the 21st century going to offer instead?” https://lnkd.in/dGx4Xe8 View in LinkedIn
