160-minute Solar Cycle

The 160-minute solar cycle was an apparent periodic oscillation in the solar surface which was observed in a number of early sets of data collected for helioseismology.

The presence of a 160 minute cycle in the Sun is not substantiated by contemporary solar observations, and the historical signal is considered by main-stream scientists to occur as the redistribution of power from the diurnal cycle as a result of the observation window and atmospheric extinction.

Famous quotes containing the words solar and/or cycle:

    Our civilization has decided ... that determining the guilt or innocence of men is a thing too important to be trusted to trained men.... When it wants a library catalogued, or the solar system discovered, or any trifle of that kind, it uses up its specialists. But when it wishes anything done which is really serious, it collects twelve of the ordinary men standing round. The same thing was done, if I remember right, by the Founder of Christianity.
    Gilbert Keith Chesterton (1874–1936)

    Oh, life is a glorious cycle of song,
    A medley of extemporanea;
    And love is a thing that can never go wrong;
    And I am Marie of Roumania.
    Dorothy Parker (1893–1967)
