Convert arcsecond to degree - Conversion of Measurement Units ›› Definition: Second. A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.710-7) of a circle.

Solar Flares and Disturbances for Radio Propagation Solar flares. Solar flares are enormous explosions that occur on the surface of the Sun. They result in the emission of colossal mounts of energy. In addition to this, the larger solar flares also eject large amounts of material mainly in the form of protons.

Corona discharge In electricity, a corona discharge is an electrical discharge brought on by the ionization of a fluid surrounding a conductor that is electrically charged. Spontaneous corona discharges occur naturally in high-voltage systems unless care is taken to limit the electric field strength.onized gases produced in a corona discharge are accelerated by the electric field, producing a movement of gas or electrical wind. The air movement associated with a discharge current of a few hundred microamperes can blow out a small candle flame within about 1 cm of a discharge point.

- Best Answer: The epicenter or epicentre (ancient Greek: επίκεντρον) is the point on the Earth's surface that is directly above the point where an earthquake or other underground explosion originates. The epicenter is directly above the hypocenter, the actual location of the energy release inside the earth.picenter is properly a geological term identifying the point of the earth's surface directly above the focus of an earthquake. No doubt this is why the Usage Panel approves of figurative extensions of its use in dangerous, destructive, or negative contexts.

Beta Volantis A parsec (symbol: pc) is a unit of length used to measure large distances to objects outside our Solar System. One parsec is the distance at which one astronomical unit subtends an angle of one arcsecond. A parsec is equal to about 3.26 light-years (31 trillion kilometres or 19 trillion miles) in length. The nearest star, Proxima Centauri, is about 1.3 parsecs (4.2 light-years) from the Sun.

- What is an Arc Most of us are familiar with an arc. The dictionary describes an electric arc as “a luminous bridge formed in a gap between two electrodes”. An Arc Flash occurs during a fault, or short circuit condition, which passes through this arc gap.

Space Weather: Sunspots, Solar Flares & Coronal Mass Ejections A solar flare is a light-speed traveling burst of x-rays and energy, while a coronal mass ejection (CME) is a giant cloud of particles emitted from the Sun. Both can affect the Earth in different ways and sometimes they happen together. Video Show: Attack of the Sun. Credit: NASA / GSFC.

Equinox The ecliptic is the apparent path of the Sun on the celestial sphere, and is the basis for the ecliptic coordinate system. It also refers to the plane of this path, which is coplanar with the orbit of Earth around the Sun (and hence the apparent orbit of the Sun around Earth).

Layers of the Skin The stratum basale is a single layer of cells primarily made of basal cells. A basal cell is a cuboidal-shaped stem cell that is a precursor of the keratinocytes of the epidermis. All of the keratinocytes are produced from this single layer of cells, which are constantly going through mitosis to produce new cells.

Parsec A corollary is that a parsec is also the distance from which a disc one astronomical unit in diameter must be viewed for it to have an angular diameter of one arcsecond (by placing the observer at D and a diameter of the disc on ES).

- Loop your guitar cable through the strap before plugging in. If you're plugging in, a good trick of the trade is to loop your guitar cable through the strap to keep it out of your way. Insert the cable between the base peg and the strap, from the back to the front of the guitar and plug it in.

Parsec The use of the parsec as a unit of distance follows naturally from Bessel's method, because the distance in parsecs can be computed simply as the reciprocal of the parallax angle in arcseconds (i.e. if the parallax angle is 1 arcsecond, the object is 1 pc from the Sun; if the parallax angle is 0.5 arcseconds, the object is 2 pc away; etc.).

Understanding Solar Renewable Energy Certificates (SRECs) In those cases, SRECs are used to account for solar electricity production. SRECs are just like RECs, but specific to electricity that comes from solar panels. For every megawatt hour (MWh) of electricity that a solar energy system produces, a corresponding SREC is created.

Electric arc An electric arc is the form of electric discharge with the highest current density. The maximum current through an arc is limited only by the external circuit, not by the arc itself. An arc between two electrodes can be initiated by ionization and glow discharge, as the current through the electrodes is increased.

- A volcanic arc is a chain of volcanoes formed above a subducting plate, positioned in an arc shape as seen from above. Offshore volcanoes form islands, resulting in a volcanic island arc. oceanic arcs form when oceanic crust subducts beneath other oceanic crust on an adjacent plate, creating a volcanic island arc. (Not all island arcs are volcanic island arcs.). 2  continental arcs form when oceanic crust subducts beneath continental crust on an adjacent plate, creating an arc-shaped mountain belt.
