The Extreme Ultraviolet Imaging Telescope (EIT) onboard the SOHO spacecraft observes the Sun's corona. It captures images over a 45 x 45 arcminute field of view in four emission line groups: FE IX, FE X, FE III, FE XV, and HE II. Data is available from the public SOHO archive and mirror archives.
Use Cases
- Analyze coronal temperature structures based on observations in the 1 to 2 MK range
- Track solar activity and plasma dynamics based on multi-wavelength extreme ultraviolet imagery
- Validate solar atmospheric models based on emission line group observations
Strengths
- Observations cover a 45 x 45 arcminute field of view
- Data is collected in four specific emission line groups
- Data is available from multiple public archive mirrors
Limitations
- Column-level documentation is absent; field semantics must be inferred after download
- Row count is unknown, which may limit suitability assessment
- Last update date is unknown; freshness unverified
