Efficiency of Electromagnetic Energy Transfer From Solar Wind to Ionosphere Through Magnetospheric Ultra‐Low Frequency Waves

Geophysical Research Letters, Volume 53, Issue 1, 16 January 2026.
Abstract Ultra‐low frequency (ULF) waves are a ubiquitous carrier of energy in geospace. However, their efficiency in transferring solar wind energy into the upper atmosphere remains a fundamental and not well‐understood question. This is due to their global presence, which cannot be fully quantified by spatially limited observations, and the need for ...

Trends in environmentally induced spacecraft anomalies [PDF]

The Spacecraft Anomaly Data Base was useful in identifying trends in anomaly occurrence. Trends alone do not provide quantitative testimony to a spacecraft's reliability, but they do indicate areas that command closer study.

DETERMINING PRAYER TIMES IN MIDNIGHT SUN COUNTRIES

Al-Hilal: Journal of Islamic Astronomy
The phenomenon of the midnight sun presents unique challenges for people living in countries that experience prolonged daylight. One issue in these regions is the application of iḥtiyāṭ (precautionary measures) in religious practices, such as determining prayer times and fasting hours according to Islamic teachings.
