Sudden Ionospheric Disturbances Generated by Solar Flares—Not so Sudden?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract It is known that solar flares generate instantaneous ionization enhancement, referred to as sudden ionospheric disturbance (SID), that occurs simultaneously across the entire dayside. In this work, we use high‐rate 1‐s data of total electron content (TEC) to analyse ionospheric response to 13 solar flares that occurred in 2003–2023.

The Cosmic Stellar Birth and Death Rates

, 2006
The cosmic stellar birth rate can be measured by standard astronomical techniques. It can also be probed via the cosmic stellar death rate, though until recently, this was much less precise.

Could Narrow Bipolar Events Serve as a Distinct Lightning Proxy for Revealing Overshooting Thunderclouds Development?

Geophysical Research Letters, Volume 53, Issue 7, 16 April 2026.
Abstract Narrow bipolar events (NBEs) are often generated in overshooting thunderclouds (OT) penetrating the stratosphere. However, how and under what conditions OT produces such discharges remains unclear. With 3‐year lightning observations and simultaneous cloud top brightness temperature measurements over South China, we developed a more accurate OT

Re-evaluation of cosmic ray cutoff terminology [PDF]

The study of cosmic ray access to locations inside the geomagnetic field has evolved in a manner that has led to some misunderstanding and misapplication of the terminology originally developed to describe particle access.
