Anomalous Substorm Signatures During Sudden Solar‐Wind Pressure Enhancements

Journal of Geophysical Research: Space Physics, Volume 130, Issue 6, June 2025.
Abstract Magnetospheric substorms, characterized by the rapid release of energy stored in the magnetotail, play a central role in space weather dynamics. These events are typically triggered by enhanced magnetic reconnection between the Earth's magnetic field and the interplanetary magnetic field (IMF).

The Galactic cosmic-ray Sun shadow observed by HAWC

, 2015
The magnetic field of the Solar corona is difficult to measure directly. However, indirect observations of the solar corona are possible using the deficit in flux of cosmic rays coming from the direction of the Sun.

Unveiling the Gannon Storm: How Ground‐Based Magnetometers Mapped Its Global Impact

Space Weather, Volume 23, Issue 6, June 2025.
Abstract The Gannon Storm, also known as the Mother's Day Storm of May 2024, ranks among the most intense geomagnetic disturbances of the space age, triggered by a powerful interplanetary coronal mass ejection. Leveraging data from over 100 globally distributed magnetic observatories, this study provides a detailed analysis of its ground‐level impacts,

Reduced ERA‐I Forecasting Skill During Forbush Decreases

Geophysical Research Letters, Volume 52, Issue 10, 28 May 2025.
Abstract Correlations between week‐long cosmic ray flux perturbations and terrestrial cloud cover have previously been identified. Still, uncertainty persists on whether the cloud response is due to a physical link involving cosmic rays or caused by random weather fluctuations.

Detection of 6 November 1997 Ground Level Event by Milagrito [PDF]

, 1999
Solar Energetic Particles from the 6 November 1997 solar flare/CME(coronal mass ejection) with energies exceeding 10 GeV have been detected by Milagrito, a prototype of the Milagro Gamma Ray Observatory.

Absence of Elevation‐Dependent Warming in Antarctica Inferred From Blue Ice Paleoclimate Records

Geophysical Research Letters, Volume 52, Issue 9, 16 May 2025.
Abstract Reconstructing the past Antarctic climate commonly involves deep drilling of ice cores. However, the ∼1% of the Antarctic ice sheet surface covered with blue ice also provides unique, yet largely unexploited paleoclimatic opportunities. Here, we analyze 444 ice samples collected in blue ice surfaces located around the Sør Rondane Mountains ...

Cosmology and Science Education: Problems and Promises

, 2012
Cosmology differs in some respects significantly from other sciences, primarily because of its intimate association with issues of a conceptual and philosophical nature.
