Geomagnetically induced currents (GIC) are electrical currents induced at the Earth's surface by rapid changes in the geomagnetic field caused by space weather events. GICs can affect the normal operation of long electrical conductor systems such as electric transmission grids and buried pipelines. The geomagnetic disturbances which induce GICs ...
Severe damage to telegraph stations. Part of solar cycle 10. The Carrington Event was the most intense geomagnetic storm in recorded history, peaking on 1–2 September 1859 during solar cycle 10. It created strong auroral displays that were reported globally and caused sparking and even fires in telegraph stations. [1]
The geomagnetic storm causing this event is believed to be the result of two separate events known as coronal mass ejections (CME) on March 10 and 12, 1989. [2] A few days before, on March 6, a very large X15-class solar flare also occurred. [3] Several days later, at 01:27 UT on March 13, a severe geomagnetic storm struck Earth.
The Global Industry Classification Standard (GICS) is an industry taxonomy developed in 1999 by MSCI and Standard & Poor's (S&P) for use by the global financial community. The GICS structure consists of 11 sectors, 25 industry groups, 74 industries and 163 sub-industries [1] into which S&P has categorized all major public companies.
Guaranteed investment contract. A guaranteed investment contract (GIC) is a contract that guarantees repayment of principal and a fixed or floating interest rate for a predetermined period of time. Guaranteed investment contracts are typically issued by life insurance companies qualified for favorable tax status under the Internal Revenue Code ...
In a news conference by NASA's Van Allen Probe team, it was stated that this third belt is a product of coronal mass ejection from the Sun. It has been represented as a separate creation which splits the Outer Belt, like a knife, on its outer side, and exists separately as a storage container of particles for a month's time, before merging once ...
v. t. e. The breast jewels (medals) worn by members of the English jurisdiction of the Order. The Red Cross of Constantine, or more formally the Masonic and Military Order of the Red Cross of Constantine and the Appendant Orders of the Holy Sepulchre and of St John the Evangelist, is a Christian fraternal order of Freemasonry.
Glass ionomer cement. A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [3]) and polyacrylic acid, an ionomer.
