Temporal variations of solar inertial mode parameters from GONG (2002–2024) and HMI (2010–2024)
Astronomy & AstrophysicsAims. We studied the temporal evolution of solar inertial modes over the solar cycle using observations from GONG and SDO/HMI. We focused our attention on the high-latitude mode with azimuthal wavenumber m = 1 and the equatorial Rossby modes with 3 ≤ m ≤

Spaceborne and spaceborn: Physiological aspects of pregnancy and birth during interplanetary flight
Experimental Physiology, Volume 111, Issue 9, Page 4015-4040, 1 September 2026.Abstract Crewed interplanetary return missions that are on the planning horizon will take years, more than enough time for initiation and completion of a pregnancy. Pregnancy is viewed as a sequence of processes – fertilization, blastocyst formation, implantation, gastrulation, placentation, organogenesis, gross morphogenesis, birth and neonatal ...

, 2019 MAJOR ADVISOR: DR. ANNO KARE (PHD) ABSTRACT The fundamental physics as introduced by the Magnetic interaction hypothesis has led to an entirely new hypothesis for solar activity and energy transformation.This important aspect has laid the bases upon which solar activities and External Magnetic Field could better be understood.

A New Declining Phase Precursor and an Early Prediction of Cycle 26 Maximum
The Astrophysical JournalThe overall level of solar activity as seen in the sunspot number (SSN) record paces both the state of the ionosphere and the amplitude and occurrence rates of extreme space weather events.

Sunspot Activity Near Cycle Minimum and What it Might Suggest for Cycle 24, the Next Sunspot Cycle [PDF]
, 2009 In late 2008, 12-month moving averages of sunspot number, number of spotless days, number of groups, area of sunspots, and area per group were reflective of sunspot cycle minimum conditions for cycle 24, these values being of or near record value.
