Modified Model for the Moon Sighting and Phases

open access: yesYanbu Journal of Engineering and Science, 2023
The modified moon sighting model is developed from the basic moon sighting model by adopting more phases. The preference of the new model is proved by its ability to predict extra three moon phases, first quarter, last quarter and dark moon. The modified

The Calibration of the 35–40 GHz Solar Radio Spectrometer with the New Moon and a Noise Source

open access: yesAstrophysical Journal Supplement Series, 2023
Calibrating solar radio flux has always been a concern in the solar community. Previously, fluxes were calibrated by matching load or the new Moon for relative calibration, and at times with the assistance of other stations’ data. Moreover, the frequency
