Automated sunspot detection and the evolution of sunspot magnetic fields during solar cycle 23
, 2010 The automated detection of solar features is a technique which is relatively underused but if we are to keep up with the flow of data from spacecraft such as the recently launched Solar Dynamics Observatory, then such techniques will be very valuable to ...

Acta Ophthalmologica, Volume 104, Issue 4, Page 355-363, June 2026.Abstract Central serous chorioretinopathy (CSC) is a chorioretinal disease characterised by serous subretinal fluid (SRF) in the macula, resulting in sudden central vision loss. It predominantly affects working‐age adults, particularly men aged 30 to 60 years.

On the Relationship Between Spotless Days and the Sunspot Cycle: A Supplement
, 2006 This study provides supplemental material to an earlier study concerning the relationship between spotless days and the sunspot cycle. Our previous study, Technical Publication (TP)-2005-213608 determined the timing and size of sunspot minimum and ...

Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract The Kelvin‐Helmholtz instability (KHI) mediates the viscous‐like solar‐terrestrial interaction by generating magnetopause surface waves that quickly become non‐linear. Basic theory predicts the locally most‐unstable linear wave dominates.

Sunspot Activity Near Cycle Minimum and What it Might Suggest for Cycle 24, the Next Sunspot Cycle
, 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.

Regional and Seasonal Effects of Geomagnetic Storms on Terrestrial Weather
Geophysical Research Letters, Volume 53, Issue 10, 28 May 2026.Abstract It has long been a mystery why small Total Solar Irradiation changes have significant effects on Earth's climate. Solar cycle correlation studies abound but cannot conclusively point to a viable physical mechanism. Here, I show that geomagnetic storms have a profound terrestrial weather impact.

Indeterminacy and business-cycle fluctuations in a two-sector monetary economy with externalities [PDF]
We consider a two-sector economy with money-in-the-utility-function and sector-specific externalities. We provide conditions on technologies leading to the existence of local indeterminacy for any value of the interest rate elasticity of money demand ...

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.

On the variation of the etesians within the sunspot cycle
, 1960 The variation of the Etesians within the sunspot cycle was examined according to observations made at the Athens Observatory during the period 1893-1958.
