The nucleus is surrounded by a “cloud” of negatively charged particles, or electrons, which move in orbits around the nucleus. Under solar maximum conditions the drag, force acting on a satellite at 500 km altitude is up to a hundred times larger than at, solar minimum. To date, only a small number of satellites have been lost due to solar events or, to collisions with debris, but something like the Carrington event, should it occur. sunspots absorb some light emitted below them.

In remote sensing, it is the measurement of electromagnetic radiation reflected or emitted from an object, is the used to identify the target and to infer its properties. Here, we consider a topic which is absolutely central to the successful operation of all satellites and spacecraft, namely the basic principles and fundamental concepts of visible light in particular and of electromagnetic radiation in general. Principles of remote sensing Detection and discrimination of objects or surface features means detecting and recording of radiant energy reflected or emitted by objects or surface material. Electromagnetic radiation is made up of waves of energy that contain electric and magnetic fields vibrating transversely and sinusoidal to each other and to the direction of propagation of the waves.

We, The Sun's electromagnetic radiation is a continuum that spans radio wavelengths through the infrared, visible, ultraviolet, x-ray, and beyond. Strictly speaking, this subject lies outside the topic of space weather; however, it is, valuable to mention it here. Today, it is said that solar activity creating a magnetic storm, Earth; a CME having a faster solar wind speed generally produces a stronger, magnetic storm. The event occurred in the middle of a large geomagnetic storm which inten-, eld now known as solar-terrestrial physics. EM radiation (the designation 'radiation' excludes static electric and magnetic and near fields) is classified by wavelength into radio, microwave, infrared, visible, ultraviolet, X-rays and gamma rays. The thermosphere expands and contracts over the, of activity, causing the density at a particular altitude to change markedly. Radiation therapy uses a form of electromagnetic radiation, commonly referred to as ionizing radiation, generated from x-rays, gamma rays, electrons, and other forms of particles. As the energy decreases (or the wavelength increases), other parts of the spectrum are UV rays, visible light, infrared, microwaves, and radiowaves. M.J.
