Sun-as-a-star Observation of White-Light Flares

, 2011
Solar flares radiates energy at all wavelengths, but the spectral distribution of this energy is still poorly known. White-light continuum emission is sometimes observed and the flares are then termed "white-light flares" (WLF).

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

Journal of Field Robotics, Volume 43, Issue 3, Page 2254-2341, May 2026.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...

The Efficiency of Electron Acceleration during the Impulsive Phase of a Solar Flare

The Astrophysical Journal Letters, 2023
Solar flares are known to be prolific electron accelerators, yet identifying the mechanism(s) for such efficient electron acceleration in solar flare (and similar astrophysical settings) presents a major challenge.

Omalizumab Therapy Results in Defined Behavioural Changes and Improvements in Quality of Life in Solar Urticaria

Photodermatology, Photoimmunology &Photomedicine, Volume 42, Issue 3, May 2026.
ABSTRACT Background Solar urticaria is a rare photodermatosis in which exquisite photosensitivity can require extreme behavioural adaptations, resulting in a substantial impact on quality of life (QoL). Omalizumab therapy has been demonstrated to improve several clinical outcome measures, but the impact on behavioural measures is poorly understood. Our

Solar Magnetic Activity and Its Terrestrial Impact through Correlations with Drought Indices

Physical Sciences and Technology
Solar activity manifests itself in the form of sunspots on the solar surface and solar flares, which can influence Earth's climatic conditions, including drought in mid-latitude regions.

Distribution of low-power solar flares by brightness rise time

Solar-Terrestrial Physics, 2018
Using data from the international flare patrol for 1972–2010, we have formed an electronic database for more than 123 thousand solar flares. We determined the mean brightness rise time (flash phase) for flare area classes and importance. We show that the

Numerical examination of plasmoid-induced reconnection model for solar flares: the relation between plasmoid velocity and reconnection rate

, 2008
The plasmoid-induced-reconnection model explaining solar flares based on bursty reconnection produced by an ejecting plasmoid suggests a possible relation between the ejection velocity of a plasmoid and the rate of magnetic reconnection.

Quasi-Periodic Pulsations in Solar Flares: new clues from the Fermi Gamma-Ray Burst Monitor

, 2011
In the last four decades it has been observed that solar flares show quasi-periodic pulsations (QPPs) from the lowest, i.e. radio, to the highest, i.e. gamma-ray, part of the electromagnetic spectrum.

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.

Methane and Ethane Emission Rates, Intensities, and Trends: Aircraft Mass Balance Insights Over the Denver‐Julesburg Basin, Fall 2021

Journal of Geophysical Research: Atmospheres, Volume 131, Issue 7, 16 April 2026.
Abstract Despite a 2.1‐fold increase in oil and gas (O&G) production from 2012 to 2021 in the Wattenberg Field (WF) area of the Denver‐Julesburg Basin (DJB), total methane (CH4) emissions have remained unchanged within measurement uncertainties (26.0 ± 6.8 t/hr in 2012, 24.0 ± 5 t/hr in 2015, and 21.4 ± 5.7 t/hr in 2021), while ethane (C2H6) emissions ...
