EEE Project: International Cosmic Day 2024

Also this year, the EEE Project participates in the International Cosmic Day (ICD) organized by DESY, which will be held on November 26, together with the in-person meeting at the Centro Fermi of the EEE Project schools. Schools that cannot attend in person will be able to follow and participate in the event online. The ICD is an occasion that allows us to deepen the study of cosmic rays and to exchange our experience with that of students around the world.

On this page, you will find the preliminary agenda and the instructions for the analysis to be carried out.

In particular, we propose to the students an analysis of data acquired by some EEE telescopes and/or POLAR detectors installed in Ny Alesund (Svalbard) during the period from April to May 2024, when the detectors observed a decrease in the muon rate due to a spectacular Solar Flare (Forbush effect).

The data to be analyzed and the details for the analysis are provided below.


By November 19, the schools of the EEE Project can send the results of their studies to This email address is being protected from spambots. You need JavaScript enabled to view it. in the form of a presentation (.ppt or .pdf) and simultaneously a summary of their analysis on a single page according to the template found here (the template is not mandatory and can be changed; the important thing is that the report fits on one A4 page).

Preliminary Agenda

  • 10:00 Welcome to the Schools

  • 10:10 Seminar (Dr. A. Oliva, INFN Bologna)

  • 11:00 Schools' reports on data analysis

  • 11:50 Event conclusion

Proposed analysis, data, and instructions

For this occasion, we will have available data acquired by the following detectors:
EEE telescopes operating with the new eco-friendly gas mixture

  • BOLO-02 (Bologna)

  • CAGL-01 (Cagliari)

  • LAQU-01 (L'Aquila)

  • VICE-01 (Vicenza)

POLA-R detectors

  • POLA-01 (Ny Alesund)

  • POLA-02 (Bologna)

  • POLA-03 (Ny Alesund)

  • POLA-04 (Ny Alesund)

The data available for all the detectors listed above cover the period from April 1, 2024, to May 15, 2024.
The data are available both in csv format (analysis via Excel or similar tools) and in root format (analysis via ROOT).
The proposed analysis can be carried out on one or more data sets.
The instructions provided are to be considered the starting point of the analysis and are based on the use of Excel (recommended choice).

The analysis regards the study of the Forbush effect connected to the exceptional solar storm of May 10, which lit up the Italian skies with a fiery red phenomenon (see Centro Fermi news, SIF Prima Pagina) and was observed by both POLA-R detectors and some EEE telescopes operating with the new eco-friendly gas mixture.

  • Download the data: zip folder containing csv and root files for the detectors listed in the period April 1 to May 15, 2024.

  • Use the instructions (download instructions) as a starting point for the analysis.

  • Once the analysis is completed, send the report as a .ppt file (maximum size 3 MB) to This email address is being protected from spambots. You need JavaScript enabled to view it. together with the summary on a single page according to the template found here (maximum size 2 MB).
