The perturbations due to the solar radiation pressure forces on the Earth's artificial satellites have been given taking into account the Moon's shadow and pre-shadow effects. The formulae are convenient when the perturbed forces are obtained by numerical methods. The study shows that the cylindrical model of the shadow is insufficient and that the conic shadow model including the pre-shadow gives more accurate results.

PlumX Metrics provide insights into the ways people interact with individual pieces of research output (articles, conference proceedings, book chapters, and many more) in the online environment. Examples include, when research is mentioned in the news or is tweeted about. Collectively known as PlumX Metrics, these metrics are divided into five categories to help make sense of the huge amounts of data involved and to enable analysis by comparing like with like.
