Abstract: This is an overview of the solar modulation of galactic cosmic rays as seen from the Earth and spacecrafts closeby, where we have put the contributions of Latin-American researchers in the global context in the last five to ten years. It is a broad topic with numerous intriguing aspects so that a research framework has to be chosen to concentrate on, therefore we have put our emphasis on measurements of the cosmic ray flux, without attempting to review all details or every contribution made in this field of research. In consequence, after establishing the basic characteristics of the cosmic radiation such as composition and energy spectrum, we focus on a few selected subjects, almost all within the framework of solar modulation of galactic cosmic rays such as Forbush decreases, periodic variations, space and atmospheric weather cosmic ray relationships, to which we add a general description of ground level enhancement observations. Controversial aspects are discussed where the appropriate results are presented, some of the challenges and prospects of key issues are also pointed out. At the end of the paper, a brief summary of the last decade Latin-American contributions to the subjects treated is given.

P. Panetta, On behalf of the EEE Collaboration Abstract: The EEE (Extreme Energy Event) Project׳s goal is the study of high energy Extensive Air Showers (EAS) over a very large area, using an array of muon telescopes, based on Multigap Resistive Plate Chambers (MRPCs). Young students are directly involved in assembling and monitoring the telescopes, with the aim to introduce them to advanced physics research. At present the array is composed of more than 40 stations, distributed on a total area of . Most of them are independently taking data since several years. A new combined run has started in February 2015, with 35 telescopes taking data simultaneously for a collected statistics larger than4×109 reconstructed events. An overview of the experiment and some results from studies on correlated muons from the same EAS, and on solar events as Forbush decreases, will be shown. Hyperlink:

Astapov, N.S. Barbashina, A.N. Dmitrieva, R.P. Kokoulin, A.A. Petrukhin, V.V. Shutenko, E.I. Yakovleva, I.I. Yashin Abstract: A new method for the analysis of spatial and angular characteristics of the cosmic ray muon flux registered in the hodoscopic mode using a single setup – the muon hodoscope – is presented. Various parameters of the muon flux anisotropy and methods of calculation of these parameters are discussed. It is shown that the horizontal projection of the muon flux relative anisotropy vector which characterizes lateral (horizontal) displacement of the muon flux angular distribution is the sensitive parameter to a variety of nonstationary processes in the heliosphere. The experimental data on the variation of the muon flux anisotropy during the passage of various irregularities in the solar wind and interplanetary magnetic field in the Earth’s vicinity are presented.
