M.

We report progress on the ongoing recalibration of the Wolf sunspot number (SN) and Group sunspot number (GN) following the release of version 2.0 of SN in 2015. This report constitutes both an update of the efforts reported in the 2016 Topical Issue

SOLAR INFLUENCES ON CLIMATE

Autor: Gray, L. J., Beer, J., Geller, M., Haigh, J. D., Lockwood, M., Matthes, K., Cubasch, U., Fleitmann, D., Harrison, G., Hood, L., Luterbacher, J., Meehl, G. A., Shindell, D., van Geel, B., White, W.

Understanding the influence of solar variability on the Earth's climate requires knowledge of solar variability, solar-terrestrial interactions, and the mechanisms determining the response of the Earth's climate system. We provide a summary of our cu

Monitoring Reactor Anti-Neutrinos Using a Plastic Scintillator Detector in a Mobile Laboratory

Autor: Carroll, J., Coleman, J., Davies, G., Lockwood, M., Metelko, C., Mills, R., Murdoch, M., Roberts, A., Schnellbach, Y., Touramanis, C.

Technology developed for the T2K electromagnetic calorimeter has been adapted to make a small footprint, reliable, segmented detector to characterise anti-neutrinos emitted by nuclear reactors. The device has been developed and demonstrated by the Un

A New Calibrated Sunspot Group Series Since 1749: Statistics of Active Day Fractions

Autor: Usoskin, I. G., Kovaltsov, G. A., Lockwood, M., Mursula, K., Owens, M., Solanki, S. K.

Although the sunspot-number series have existed since the mid-19th century, they are still the subject of intense debate, with the largest uncertainty being related to the "calibration" of the visual acuity of individual observers in the past. Daisy-
