Heliophysics Bigg Year

Heliophysics Bigg Year
The term "Heliophysics Bigg Year" doesn't appear to be a widely recognized or established concept in the field of heliophysics or astronomy as of my last knowledge update in September 2021. It's possible that it could be a specialized or emerging term or event in the field that has gained significance after my last update. If you have more context or specific questions about heliophysics or related topics, feel free to ask, and I'll do my best to provide information based on my existing knowledge.
