A sudden fine-scale bright kernel captured by Hi-C Flare in 11 MK emission during an M1.6-class solar flare's post-maximum phase
Sanjiv K. Tiwari, Navdeep K. Panesar, Ronald L. Moore +17
On April 17, 2024, the third successful Hi-C sounding rocket flight, Hi-C Flare, recorded coronal images in Fe XXI 129 A emission from 11 MK plasma during the post-maximum phase of…

Determining the magnetic field of active region plages using the whole CLASP2/2.1 spectral window
David Afonso Delgado, Tanausú del Pino Alemán, Javier Trujillo Bueno +16
The Chromospheric LAyer SpectroPolarimeter missions, CLASP2 and CLASP2.1, demonstrated that the near-UV spectral region between 279.30 and 280.68 nm is suitable for studying the ma…
