Using the Neutron Star Interior Composition Explorer (NICER) and various ground-based telescopes, an international team of astronomers have performed observations of a strong X-ray superflare which occurred in 2022 on a giant star known as HD 251108. Results of the observational campaign, published Oct. 4 on the pre-print server arXiv, provide more insights into the flaring activity of this star.
