Direct Observation of Wilsonian Electrons in Thunderstorms
A. Chilingarian, T. Karapetyan, B. Sargsyan
We analyze electron rich Thunderstorm Ground Enhancements (TGEs) detected at Aragats using the SEVAN Light spectrometer, which can separate charged and neutral particles and recons…
Continued activity of the 25th cycle: largest in 20 years. Ground-level enhancement and Forbush decrease
B. Sargsyan, A. Chilingarian
After a very calm 24th solar activity cycle, the 25th cycle has already seen several interesting events. A Ground Level Enhancement GLE77 was observed on 11 November 2025 following…
Solar neutron and muon detection on November 11, 2025: First simultaneous recovery of energy spectra
A. Chilingarian, B. Sargsyan, L. Kozliner +1
Ground Level Enhancement (GLE) events provide rare opportunities to study high-energy solar particle acceleration through direct detection of secondary radiation at ground level. O…
The largest Forbush decrease in 20 years: Preliminary analysis of SEVAN network observations
A. Chilingarian, T. Karapetyan, B. Sargsyan
We present a preliminary analysis of the largest Forbush Decrease (FD) observed in solar cycle 25 using SEVAN network data. Triggered by consecutive Earth-directed CMEs on May 30 a…
