SUN AND OZONE. “As the energetic particles can penetrate to 20–40 km altitude (depending on their energy), they also affect the middle and upper atmospheric chemistry while colliding with the atmospheric constituents: The particle precipitation leads to an enhancement of NO2 in the atmosphere, which in turn is a catalyst for ozone destruction. This way the solar activity also affects the long-term balance of the atmospheric chemistry.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

ERUPTIVE SOLAR FLARE YESTERDAY. “Solar activity has been fairly boring during the past few days but a surprise solar flare woke us up. A long duration C7.41 solar flare peaked today at 16:32 UTC. Sunspot region 2790 is to blame and that is a sunspot region facing Earth! Long duration solar flares are known to produce coronal mass ejections so the question is... was this an eruptive event? C7.4 solar flare. Monday, 7 December 2020 - 19:45 UTC. The answer to that question is a huge yes!“ https://www.spaceweatherlive.com/en/news/view/422/20201207-c7-4-solar-flare.html View in LinkedIn

THE COPERNICAN REVOLUTION AND THE REFORMATION, 1500-1700. “Just as Copernicus started with the geocentric , but reached a heliocentric conception of the physical world, Luther began with an anthropocentric or egocentric conception of religion, but came to a theocentric conception.” https://lnkd.in/d5CXHc3 View in LinkedIn

“SOLAR ENERGETIC PARTICLES affect the space environment in multiple ways. In the outer magnetosphere (especially near the geostationary region), their presence is a hazard for the satellite systems and instrumentation. If they become trapped in the inner magnetosphere dipolar field, they populate the van Allen belts, residing in the magnetosphere for extended periods.” https://link.springer.com/article/10.12942/lrsp-2007-1 View in LinkedIn

SOLAR HEAT. “This most familiar form of the Sun’s influence on the Earth is a factor also for space weather: Increases of the solar irradiance cause heating of the upper atmosphere, which affects the drag experienced by low-Earth-orbiting satellites.” https://link.springer.com/article/10.12942/lrsp-2007-1 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

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
