Application of historic datasets to understanding open solar flux and the 20th-century grand solar maximum:2. Solar observations

Autor: Lockwood, M. (Mike), Owens, M. J. (Mathew J.), Yardley, S. L. (Stephanie L.), Virtanen, I. O. (Iiro O. I.), Yeates, A. R. (Anthony R.), Muñoz-Jaramillo, A. (Andrés)

We study historic observations of solar activity from the 20th-century rise towards the peak of the Modern Grand Solar Maximum (MGSM) and compare with observations of the decline that has occurred since. The major difference in available solar observ

Solar energetic-particle ground-level enhancements and the solar cycle

Autor: Owens, M. J. (Mathew J.), Barnard, L. A. (Luke A.), Pope, B. J. (Benjamin J. S.), Lockwood, M. (Mike), Usoskin, I. (Ilya), Asvestari, E. (Eleanna)

Severe geomagnetic storms appear to be ordered by the solar cycle in a number of ways. They occur more frequently close to solar maximum and the declining phase, are more common in larger solar cycles, and show different patterns of occurrence in odd

The Maunder minimum and the Little Ice Age:an update from recent reconstructions and climate simulations

Autor: Owens, M. J. (Mathew J.), Lockwood, M. (Mike), Hawkins, E. (Ed), Usoskin, I. (Ilya), Jones, G. S. (Gareth S.), Barnard, L. (Luke), Schurer, A. (Andrew), Fasullo, J. (John)

The Maunder minimum (MM) was a period of extremely low solar activity from approximately AD 1650 to 1715. In the solar physics literature, the MM is sometimes associated with a period of cooler global temperatures, referred to as the Little Ice Age (

Assessment of different sunspot number series using the cosmogenic isotope ⁴⁴Ti in meteorites

Autor: Asvestari, E. (Eleanna), Usoskin, I. G. (Ilya G.), Kovaltsov, G. A. (Gennady A.), Owens, M. J. (Mathew J.), Krivova, N. A. (Natalie A.), Rubinetti, S. (Sara), Taricco, C. (Carla)

Many sunspot number series exist suggesting different levels of solar activity during the past centuries. Their reliability can be assessed only by comparing them with alternative indirect proxies. We test different sunspot number series against the
