Even while the station had authorization for nighttime operation by this period, WOKG primarily operated during the daytime hours ( excluding whenever high school play-by-play would air ).

With respect to nighttime assignments, the degree of skywave service and interference is determined by skywave curves ( figs. 1 and 2 of sec. 3.190 of the rules ) giving average skywave values.

During nighttime hours, because of the intense skywave propagation then prevailing, no large number of stations can be permitted to operate on one of these channels, if the wide area service for which these frequencies are assigned is to be rendered satisfactorily by the dominant stations which must be relied upon to render it.

Most of the syndicated programs were " nighttime " adaptations of network daytime game shows ; these game shows originally aired once a week, but by the late 1970s and early 1980s most ouf the games had transitioned to five days a week.

Other than the heat retention properties of urban areas, the nighttime maximum in urban canyons could also be due to the blocking of " sky view " during cooling: surfaces lose heat at night principally by radiation to the comparatively cool sky, and this is blocked by the buildings in an urban area.

There were reports that the number of residents increased by 60 % during the 1990s to about 25, 000 although a second estimate ( based on the 2000 census based on a different map ) places the residential ( nighttime and weekend ) population in 2000 at 12, 042.

In the early Imperial era, Ovid describes the opening of Cerealia ( mid to late April ) with a horse race at the Circus, followed by the nighttime release of foxes into the stadium, their tails ablaze with lighted torches.

Due to the differences between daytime and nighttime ionospheric propagation at mediumwave frequencies, it is common for AM broadcast stations to change between day ( groundwave ) and night ( skywave ) radiation patterns by switching the phase and power levels supplied to the individual antenna elements ( mast radiators ) daily at sunrise and sunset.

The increasing costs, both of organization and of competing, as well as safety concerns, have, over the last twenty years, brought progressively shorter rallies, shorter stages and the elimination of nighttime running, scornfully referred to as " office hours rallying " by older hands.

The term " artificial moonlight " was used to distinguish illumination provided by searchlights from that provided by normal moonlight, which was referred to as " movement light " in nighttime manoeuvers.

Nickelodeon does have broadcast access to most feature films based on or that served as the basis for original series produced by the channel ( such as Barnyard and The SpongeBob SquarePants Movie ); the majority of live-action feature films produced under the Nickelodeon Movies banner are licensed for broadcast by various television outlets, primarily cable networks ( however, Nickelodeon has aired a small number of live-action features from Nickelodeon Movies including Angus, Thongs and Perfect Snogging and Good Burger, which have aired on the channel's Nick at Nite nighttime block ).

But during nighttime hours the skywave radiations are reflected from the ionosphere, thereby creating the possibility of one station's rendering service, via skywave, at a much greater distance than it can through its groundwave signal, and at the same time vastly complicating the interference problem because of the still greater distance over which these skywave signals may cause interference to the signals of stations on the same and closely adjacent frequencies.

Because of the difference between daytime and nighttime propagation conditions, it has been necessary to evolve different allocation structures for daytime and nighttime broadcasting in the AM band, with many more stations operating during the day than at night.

The same restrictions apply after local sunset in the case of class 3, stations operating on regional channels, which after that time are required to operate under nighttime restrictions in order to protect each other.

Similarly, on the regional channels many class 3, stations have been assigned either to operate daytime only or to operate nighttime with directional antennas and/or lower power.

As a result, many broadcast stations are required as a condition of license to reduce their broadcasting power significantly ( or use directional antennas ) after sunset, or even to suspend broadcasting entirely during nighttime hours.

On other frequencies, there are " Regional Channels " where most stations on these frequencies either reduce power or change to a directional antenna system at nighttime to help reduce co-channel interference to each other's signals.

In the United States, there are six " Local Channel " frequencies, also known as " graveyarders " where nearly every station on those frequencies has the same power and antenna pattern both day and night and, as a result of skywave propagation, there is normally massive co-channel interference in rural areas on these frequencies, often making it difficult, if not impossible, to understand what's being said on the nearest local station on the respective channel, or the other distant stations which are bouncing on the same channel, during the nighttime hours.

* Cancellation of signal: In addition, many AM stations, including but not limited to the clear channel stations, often experience cancellation of their own signals within the inner and outer fringes of their normal groundwave coverage areas at nighttime due to the stations ' individual skywave signals reaching the listeners ' receivers at or near equal strength to the stations ' individual groundwave signals ; this phenomenon is very similar to the multipath interference experienced on FM Radio in the VHF band within mountainous regions and urban areas due to signals bouncing off of mountains, buildings, and other structures, except that the groundwave-skywave cancellation occurs almost exclusively at nighttime when skywave propagation is present.

Certain mediumwave frequencies were set aside under the North American Radio Broadcasting Agreement ( NARBA ) for nighttime use by only one or two specific AM stations, covering a wide area via skywave propagation ; these frequencies were known as the clear channels, and the stations on them are thus clear-channel stations.

Occlusal splints ( also called night guards or mouth guards ) reduce nighttime clenching in some patients, while increasing clenching activity in other patients.

Plouton Helios is mentioned in other literary sources in connection with Koure Selene and Helios Apollon ; the sun on its nighttime course was sometimes envisioned as traveling through the underworld on its return to the east.

Clear-channel stations, unlike all other AM stations in North America, have a secondary service area — that is, they are entitled to protection from interference to their nighttime skywave signals.

AM IBOC in the United States still faces some serious technological challenges of its own, including nighttime interference with other stations.
