These measurements can be considered as secondary realizations ( in a metrological sense ) of the primary definition of ET in terms of the solar motion, after a calibration of the mean motion of the Moon with respect to the mean motion of the Sun.

To reach the largest television audience, the speech, once given during the day, is now typically given in the evening, after 9 pm ET.

This blackout was narrowly avoided when a zero-hour deal was reached shortly after 12 Midnight ET on January 1, 2009.

Poor ratings caused this experiment to be dropped after one season, with MNF once again moving to 9 p. m. in, though in many NFL markets, the 8pm ET hour from 1999 until 2006 was replaced by affiliates with locally-produced sports discussion and coaches shows programmed locally, with ABC programming in that hour moved to late night or weekend slots ; by the end of the ABC run, the 8pm timeslot was filled with either newsmagazines and short-lived reality television programs which failed to make any ratings headways due to affiliate pre-emptions.

On January 21, 2006, just days after the unexpected death of his wife Ramona, Bell announced he would host Coast to Coast AM every Saturday and Sunday evening, and that former weekend host Ian Punnett would work a new live prefeed program for the four hours preceding Bell's slot on Saturday nights ( 9: 00 pm – 1: 00 am ET ).

The first version to be fully deployed, WE. 177B, was delivered to the Royal Air Force in September 1966 followed by deliveries of the WE. 177A to the Royal Navy beginning in 1969, and the RAF in 1971, after a delay caused by the need to produce the ET. 317 warhead for the UK Polaris A3T first ; and was followed by WE. 177C deliveries to the RAF.

In its early years, ET was co-produced with TeleRep ( who left after 1991 ), Cox Broadcasting ( who left after 1997 ), and Taft / Great American Broadcasting ( who left after 1991 ).

During Bellows ' years the series also developed a series of investigative reports about Hollywood's drug use and hiring practices ; but during the 1996 – 97 season ET began to include more sensational fare, featuring paid exclusive interviews with controversial and infamous newsmakers of the day, including disgraced Olympic figure skater Tonya Harding, who became notorious for her role in the conspiracy to physically attack rival Nancy Kerrigan at a 1994 U. S. Figure Skating Championships practice session ; Amy Fisher, who appeared with Joey and Mary Jo Buttafuoco, reunited after Fisher's infamous assault on Mrs. Buttafuoco ; convicted child molester Mary Kay Letourneau, who married Vili Fualaau ; and attorney Howard K.

ET ( the Saturday morning infomercial block was eliminated after March 25, 2011 ); as such it is one of only three English-language cable movie channels in the United States to air infomercials ( along with Hallmark Movie Channel and Lifetime Movie Network ); others, including sister channels Sundance Channel and IFC, run a 24-hour schedule of films with some series programming.

The show aired at 10: 30 PM ET, the time slot just after Ashlee's sister Jessica Simpson's already successful reality show Newlyweds: Nick and Jessica.

For example, it might begin as early as 9: 30pm ET ( i. e. immediately following a 7: 00pm ET NHL game ), or as late as after midnight ET if delayed due to live events.

ET, both WABC and WPVI were removed from Cablevision leaving a black screen in their place, confirming the rumors that if a deal with Cablevision and ABC was not reached by midnight, the network and other Disney-owned channels would go off the air.

Close equality between the ET second with the later SI second ( as defined with reference to the cesium atomic clock ) has been verified to within 1 part in 10 < sup > 10 </ sup >.

The difference between ET and UT is called ΔT ; it changes irregularly, but the long-term trend is parabolic, decreasing from ancient times until the nineteenth century, and increasing since then at a rate corresponding to an increase in the solar day length of 1. 7 ms per century ( see leap seconds ).

During its first full year, the channel was available to more than 532, 000 subscribers in the U. S. In April 1984, the channel extended its programming day to 18 hours a day by adding two hours to its late night schedule, with the channel now broadcasting daily from 7 a. m .- 1 a. m. ET / PT.

It debuted on July 1, 1985 and broadcasts over Nickelodeon on Sunday through Thursdays from 8 p. m .- 7 a. m., Fridays from 9 p. m .- 7 a. m. and Saturdays from 10 p. m .- 7 a. m. ET / PT.

ET ( 1 a. m. CT ).

Electrothermal AAS ( ET AAS ) using graphite tube atomizers was pioneered by Boris V. L ’ vov at the Saint Petersburg Polytechnical Institute, Russia, since the late 1950s, and further investigated by Hans Massmann at the Institute of Spectrochemistry and Applied Spectroscopy ( ISAS ) in Dortmund, Germany.

ET was an independent time-variable, proposed ( and its adoption agreed ) in the period 1948 – 52 with the intent of forming a gravitationally uniform time scale as far as was feasible at that time, and depending for its definition on Simon Newcomb's Tables of the Sun ( 1895 ), interpreted in a new way to accommodate certain observed discrepancies.

ET, in turn, can now be seen ( in light of modern results ) as close to the average mean solar time between 1750 and 1890 ( centered on 1820 ), because that was the period during which the observations on which Newcomb's tables were based were performed.

An impression has sometimes arisen that ephemeris time was in use from 1900: this probably arose because ET, though proposed and adopted in the period 1948 – 1952, was defined in detail using formulae that made retrospective use of the epoch date of 1900 January 0 and of Newcomb's Tables of the Sun.

Ephemeris time ( ET ), adopted as standard in 1952, was originally designed as an approach to a uniform time scale, to be freed from the effects of irregularity in the rotation of the earth, " for the convenience of astronomers and other scientists ", for example for use in ephemerides of the Sun ( as observed from the Earth ), the Moon, and the planets.

ET was used for the calibration of atomic clocks in the 1950s.

The atomic clocks gave rise to the atomic time scale, and to what was first called Terrestrial Dynamical Time and is now Terrestrial Time, defined to provide continuity with ET.

The alien character of Prot in the book trilogy by Gene Brewer and played by Kevin Spacey in the movie K-PAX, like Proteus was said to embody, was a modernized " shape shifter " and magical type of advanced mystical ET who " walked in " to humanoid bodies, and shared wisdom and insights into the human condition.

The orbiter was lifted up on a sling very similar to the one used at Kennedy Space Center and placed inside the Dynamic Test Stand building, and there mated to the Vertical Mate Ground Vibration Test tank ( VMGVT-ET ), which in turn was attached to a set of inert Solid Rocket Boosters ( SRB ) to form a complete shuttle launch stack, and marked the first time in the program's history that all Space Shuttle elements, an Orbiter, an External Tank ( ET ), and two SRBs, were mated together.

TT shares the original purpose for which ET was designed, to be free of the irregularities of mean solar time.

It was designed for continuity with ET, and it runs at the rate of the SI second, which was itself derived from a calibration using the second of ET ( see, under Ephemeris time, Redefinition of the second and Implementations.

Because of the historical difference between TAI and ET when TT was introduced, the TAI realization of TT is defined thus:

Prior to the closing of the Vandenberg facility, orbiters were transported from the OPF to the VAB on their undercarriages, only to be raised when the orbiter was being lifted for attachment to the SRB / ET stack.

* Ephemeris Time ( ET ) was from 1952 to 1976 an official time scale standard of the International Astronomical Union ; it was a dynamical time scale based on the orbital motion of the Earth around the Sun, from which the ephemeris second was derived as a defined fraction of the tropical year.

For the calculation of ephemerides, TDB was officially recommended to replace ET, but deficiencies were found in the definition of TDB ( though not affecting T < sub > eph </ sub >), and these led to the IAU defining and recommending further time scales, Barycentric Coordinate Time ( TCB ) for use in the solar system as a whole, and Geocentric Coordinate Time ( TCG ) for use in the vicinity of the Earth.
