Space Weather, Volume 24, Issue 8, August 2026.Abstract This study presents a novel multitask deep learning framework that integrates models designed for simultaneous, multi‐horizon forecasting of Hp60 and Disturbance storm time (Dst) indices with lead times up to 3 hr. Using a Long Short‐Term Memory architecture, the models capture both mid‐latitude variability and the ring current dynamics. Input

Implications of Using Spheroidal “Cone Model” CMEs in Solar‐Wind Models
Space WeatherSpace‐weather forecasting requires advanced prediction of the arrival time and properties of coronal mass ejections (CMEs) in near‐Earth space. Kinematic properties of CMEs close to the Sun—such as speed, direction and angular width—are routinely ...

Space Weather, Volume 24, Issue 8, August 2026.Abstract The period from 1 to 14 May 2024 was marked by some of the most intense solar activity of Solar Cycle 25, including multiple X‐class flares, fast coronal mass ejections (CMEs), and diverse solar radio emissions. We present observations from the Mexican e‐Callisto network (REC‐Mx), including long‐duration continuum emissions (CTMs), Type II ...

Space Weather, Volume 24, Issue 8, August 2026.Abstract Large ionospheric disturbances were observed over Europe during the extreme geomagnetic storm on 10 May 2024. This study analyzes GNSS‐derived total electron content (TEC) and all‐sky imager data to investigate these disturbances. Pronounced TEC enhancements, irregularities, and strong gradients were confined to the auroral region above the ...

The Astrophysical Journal, 2001 Narrow coronal mass ejections (CMEs), defined arbitrarily as events whose apparent angular width is 15° or less, are a small subset of all CMEs. Little is known of the properties of these events and whether these properties differ from those of the larger, more typical CMEs. We have included in this study 15 narrow CMEs observed in the period from 1999

Space Weather, Volume 24, Issue 8, August 2026.Abstract This paper quantitatively characterizes dB/dt peaks at four African equatorial‐ and low‐latitude stations, along latitudinal and local‐time gradients across different phases of selected geomagnetic storms. We investigate dB/dt response for intense geomagnetic storms, Dst ≤ −100 nT observed during solar cycle 24 over four stations in the ...

Modeling Polarized Radio Sounding Observations of a Coronal Mass Ejection
The Astrophysical JournalCoronal mass ejections (CMEs) evolve significantly as they propagate from the Sun to the Earth, so remote observations of their changes in speed, strength of the magnetic field, density, and overall structure are critical for predicting their arrival ...

The Journal of Clinical Hypertension, Volume 28, Issue 8, August 2026.ABSTRACT Renal artery variations are recognized as potential contributors to hypertension through altered renal perfusion and activation of renin–angiotensin system. However, their clinical and hemodynamic significance in children remains unclear. This retrospective study included 14 pediatric patients (0–18 years) with hypertension and renal artery ...

Identifying Coronal Mass Ejection Active Region Sources: An Automated Approach
The Astrophysical JournalIdentifying the source regions of coronal mass ejections (CMEs) is crucial for understanding their origins and improving space weather forecasting. We present an automated algorithm for matching CMEs detected by the Large Angle Spectrometric Coronagraph ...

Can acromegaly be controlled in all cases?
Journal of Neuroendocrinology, Volume 38, Issue 8, August 2026.Abstract Acromegaly is a rare disease, due in most of the cases to a growth hormone (GH)‐secreting pituitary adenoma (PA), namely neuroendocrine tumour (PitNET). The treatment of patients with acromegaly is multimodal and multi‐step, including surgery, medical therapies, and radiotherapy.
