The Secret Series is a series of 'secret'-themed adventure novels written by Pseudonymous Bosch, who is suspected to be Raphael Simon.
 The series centers on three middle school children, Cass, Max-Ernest, and Yo-Yoji, and their adventures as members of the Terces Society ("secret society" spelled backwards), a group that keeps a mysterious Secret from being found out or stolen by the Midnight Sun society.
 One of the subplots of the series is the alchemists of the Midnight Sun searching for the secret to immortality, and the Terces Society's plans to stop them.
The "Fairbanks Daily News-Miner" Midnight Sun Run is a ten kilometer road running event, held annually since 1983 in Fairbanks, Alaska, that attracts participants from across the United States and Canada.
 The race takes place on the third Saturday of June each year, starting at 10 pm with the boom of a cannon that can be heard throughout Fairbanks.
 Despite its late evening start, there is no need for streetlights or flashlights, as the summer solstice sun shines brightly from start to finish and beyond.
 Proceeds from the race benefit United Way of the Tanana Valley and local student athletes through scholarships.
 In recent years the race has attracted over 3,000 participants, due in part to its special feature of running in the daylight of the midnight sun.
The Midnight Sun Solar Rayce Car Team is a Canadian solar car race team affiliated with the University of Waterloo of Waterloo, Ontario.
 Founded in 1988, the Midnight Sun team is a student-run organization which designs and builds a solar vehicle every two to three years to compete in two solar challenges; the World Solar Challenge, held in Australia, and the American Solar Challenge, held in the United States.
 The team's roster recruits from every department on campus, resulting in a diverse, innovative team and work environment.
The midnight sun is a natural phenomenon that occurs in the summer months in places north of the Arctic Circle or south of the Antarctic Circle, when the sun remains visible at the local midnight.
 Around the summer solstice (approximately 21 June in the Northern Hemisphere and 22 December in the Southern Hemisphere) the sun is visible for the full 24 hours, given fair weather.
 The number of days per year with potential midnight sun increases the closer towards either pole one goes.
 Although approximately defined by the polar circles, in practice the midnight sun can be seen as much as 55 miles (90 km) outside the polar circle, as described below, and the exact latitudes of the farthest reaches of midnight sun depend on topography and vary slightly year-to-year.
The polar night occurs in the northernmost and southernmost regions of the Earth when the night lasts for more than 24 hours.
 This occurs only inside the polar circles.
 The opposite phenomenon, the polar day, or midnight sun, occurs when the Sun stays above the horizon for more than 24 hours.
 "Night" is understood as the center of the Sun being below a free horizon.
 Since the atmosphere bends the rays of the Sun, the polar day is longer than the polar night, and the area that is affected by polar night is somewhat smaller than the area of midnight sun.
 The polar circle is located at a latitude between these two areas, at the latitude of approximately 66.5 degrees.
 In the most northern city of Sweden, Kiruna, at 67°51'N, the polar night lasts for around 28 twenty-four-hour periods, while the midnight sun lasts around 50 twenty-four-hour periods.
 While it is day in the Arctic Circle it is night in the Antarctic Circle.

 The song peaked at number-one the Radio Top 50 and charted within the top ten in two other Romanian charts.
 In the official Romanian Top 100 it peaked at number-ten, thus making it Elena's fifth song to enter the top ten in Romania, after "Soarele meu", "Vocea ta", "The Balkan Girls" and "Disco Romancing".
