EEE Project: International Cosmic Day 2024

Also this year, the EEE Project is participating in the International Cosmic Day organized by DESY, which will be held on November 26, coinciding with the in-person meeting at the Centro Fermi for the schools involved in the EEE Project. Schools that cannot attend in person will be able to follow and participate in the event online. ICD is an opportunity for us to deepen our study of cosmic rays and exchange our experience with students from all over the world.

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

In particular, we propose students to analyze data collected by some EEE telescopes and/or POLAR detectors installed in Ny Ålesund (Svalbard) during the period from April to May 2024, when the detectors observed a decrease in the muon rate caused by 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 participating in 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 you can find here (the template is not mandatory and can be modified, but the report must fit on an A4 page).

Preliminary agenda:

  • 10:00 AM Welcome to the Schools

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

  • 11:00 AM Schools' reports on data analysis

  • 11:50 AM Conclusion of the event

Proposed analysis, data and instructions:

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

  • BOLO-02 (Bologna)

  • CAGL-01 (Cagliari)

  • LAQU-01 (L'Aquila)

  • VICE-01 (Vicenza)

POLAR detectors:

  • POLA-01 (Ny Ålesund)

  • POLA-02 (Bologna)

  • POLA-03 (Ny Ålesund)

  • POLA-04 (Ny Ålesund)

  1. The available data for all the detectors listed cover the time period from April 1, 2024 to May 15, 2024.
  2. The data is available in both CSV format (to be analyzed using Excel or similar software) and ROOT format (to be analyzed with ROOT).
  3. The proposed analysis can be done on one or more datasets.
  4. The provided instructions are to be considered as a starting point for the analysis and are based on using Excel (recommended choice).

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