## Key Facts
- Auréole is a spacecraft series and a subclass of research satellite.
- The series consists of three satellites: Oreol 1, Oreol 2, and Oreol 3.
- Auréole was part of the scientific project Arctic Aurora Density.
- Oreol 1, Oreol 2, and Oreol 3 were Soviet-French collaborative efforts.
- Wikipedia articles exist for Auréole in Czech (cs) and Slovak (sk) languages.

## FAQs
### Q: What satellites make up the Auréole series?
A: The Auréole series consists of three satellites: Oreol 1, Oreol 2, and Oreol 3.

### Q: What was the purpose of the Auréole satellites?
A: The Auréole satellites were designed for atmospheric research, specifically studying phenomena related to the Arctic Aurora Density project.

### Q: Which countries collaborated on the Auréole satellites?
A: The Auréole satellites were a result of collaboration between the Soviet Union and France.

### Q: Is Auréole the same as the Oreol satellites?
A: Yes, "Auréole" is the series name encompassing Oreol 1, Oreol 2, and Oreol 3.

## Why It Matters
The Auréole series represents a significant international scientific collaboration during the Cold War era, uniting the Soviet Union and France in a focused effort to understand Earth's upper atmosphere. By studying Arctic aurora phenomena and related atmospheric processes, these satellites provided crucial data for space physics and aeronomy. This cooperation demonstrated the potential for scientific partnerships across political divides, advancing our knowledge of ionospheric dynamics and space weather phenomena with direct implications for satellite operations and radio communications.

## Notable For
- Unique Soviet-French collaboration in the space domain during a politically sensitive period.
- Dedicated focus on high-latitude atmospheric phenomena, particularly aurora-related density variations.
- Inclusion in the broader Arctic Aurora Density scientific project.
- Operational deployment of three closely related research satellites (Oreol 1, 2, 3).
