Scientists predict that on July 22, the day will be about a millisecond shorter than the standard 24 hours due to Earth's variable rotation. On July 9, the day was shortened by nearly 1.4 milliseconds. Factors influencing Earth's speed include gravitational pulls, atmospheric conditions, and core movements. Long-standing research has tracked Earth's rotation through ancient observations and modern radio telescope data aimed at quasars. This information is compiled and used to make forecasts by the International Earth Rotation and Reference Systems Service.
The International Earth Rotation and Reference Systems Service has predicted that July 22 could come out about a millisecond short of a standard 24-hour spin.
Dennis McCarthy notes that variations in the Earth’s rotation are influenced by factors such as the gravitational influence of the moon and the movements of the Earth's liquid core.
