Enable an AI agent to recognise a solar flare, assess its observed evolution and evidence, and determine which monitoring or impact-assessment actions are justified.
Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify. Unreviewed either way.

Purpose and description
Enable an AI agent to recognise a solar flare, assess its observed evolution and evidence, and determine which monitoring or impact-assessment actions are justified.
A solar flare is a transient release of stored magnetic energy in the Sun's atmosphere that heats plasma, accelerates particles, and produces enhanced electromagnetic emission across a broad spectrum.
It can be Match detections across instruments and catalogues while retaining competing event boundaries.; Request observations that resolve uncertain source locations, missed peaks or overlapping events.; Compare flare intensity and evolution using compatible bands and documented measurement conventions.; Update event state and classification as observations become available or are revised.; Link independently identified eruptions and receiving-system effects using explicit association evidence.; Route monitoring or mitigation recommendations through a relevant operational model when its evidence thresholds are met..
Distinguishing features
Require evidence of a transient solar radiative enhancement attributable to an energy-release event, rather than treating every bright solar feature as a flare.
Distinguish flare radiation from a coronal mass ejection: evidence of brightening does not by itself establish expelled plasma.
Distinguish the solar event from a receiving-system disturbance: a radio interruption or geomagnetic change alone does not identify a flare.
Treat a persistent active region as the source environment, not as an indefinitely continuing flare.
Verify that the source is the Sun; an analogous event on another star belongs to a stellar-flare model.

Characteristics
- Event identification status
- candidate | confirmed | disputed | rejected; supporting criteria required Prevents an unverified brightening or automated detection from becoming an unquestioned flare record.
- Solar source location
- Heliographic coordinates in degrees with coordinate convention and timestamp; unknown permitted Supports source matching, visibility assessment and separation of concurrent events.
- Source active region
- Referenced active-region record with attribution confidence; unassigned permitted Connects the event to its magnetic setting without equating a region with one flare.
- Observed spectral irradiance or band irradiance
- W m^-2 nm^-1 or W m^-2 as appropriate, with passband, observer location, time and background treatment Makes radiation measurements interpretable and avoids comparing incompatible observing bands.
- Soft X-ray flare class
- Reported class and numeric multiplier, with classification convention, instrument and quality flags; unavailable permitted Provides a conventional intensity descriptor without presenting it as total energy or universal impact severity.
- Event timing
- Start, peak and end timestamps with time standard, observing band and detection rule Allows event matching while preserving differences between operational and physical boundaries.
- Observational completeness
- Record gaps, saturation, occultation, cadence limitations and source confusion Shows when a measured peak, duration or apparent absence may be misleading.
- Estimated released energy
- J, with energy component, estimation method, uncertainty and measured versus inferred status Separates component-specific estimates from claims about the whole event's energy budget.
- Associated eruption or particle event
- Links to separately identified events with association evidence and confidence Preserves relevant connections without assuming that every flare has the same accompanying phenomena.
- Receiving-location effect
- Linked observed or predicted effect, receiving location, interval, mechanism and attribution confidence Supports decisions based on a specified exposure and mechanism rather than flare class alone.

Flare identity and boundaries Establishes what qualifies as this solar-flare event and how it is separated from neighbouring phenomena.
An agent must identify one defensible event before combining observations or assigning consequences.
Solar-flare recognition
Tests whether the observed transient supports a solar-flare identification.
Qualifying radiative transient
Record the observations and recognition criteria supporting the flare label, including plausible alternative explanations.
- Which observed solar radiation signatures qualify this transient as a flare under the adopted definition? definition
- What evidence distinguishes it from persistent active-region emission, another solar transient or an instrumental artefact? boundary
Event separation
Handles repeated brightenings, overlapping sources and duplicate catalogue entries.
Single-event delimitation
Preserve the evidence and operational rules used to group detections into one flare or separate flares.
- Do successive peaks belong to one flare or separately identified events, and which temporal and spatial criteria decide? boundary
- Which catalogue records identify this same event, and where do their boundaries disagree? provenance
Solar source and energy release Connects the flare to its observed solar location and evidence about its physical development.
Source geometry and mechanism evidence determine how observations can be interpreted and which physical claims remain tentative.
Source localisation
Identifies the emitting region and its visibility from each observing platform.
Location and visibility
Record coordinate conventions, source-region attribution and any hidden or unresolved emission.
- Where is the flare located on the Sun, in which coordinate frame and at what reference time? measurement

Energy-release evidence
Separates measured signatures from interpretations of magnetic energy conversion.
Mechanism and energy accounting
Record evidence for proposed energy-release mechanisms and keep thermal, particle and radiative energy estimates distinct.
- Which observations support the proposed magnetic energy-release interpretation, and which parts depend on a model? provenance
- Which energy components have been estimated, by what method and with what uncertainties or possible double counting? measurement
Radiation measurement and classification Makes flare brightness measurements and intensity labels comparable and traceable.
A flare class or peak value is useful only when its observing band, convention and limitations are known.
Spectral observations
Organises radiation evidence by observing band and instrument.
Interpretable radiation measurements
Retain the passband, units, sampling, observing geometry and background treatment attached to each measurement.
- Which spectral bands were observed, and what quantities, units and observing locations do their measurements represent? measurement
- Which instrument products and processing versions support the measurements, including background subtraction and quality flags? provenance
Intensity labels
Records operational classification while constraining its interpretation.
Traceable flare class
Tie every reported class to its measurement convention and distinguish that label from energy or impact estimates.
- What classification system, passband and peak-selection rule produced the reported flare class? definition
- Does saturation, occultation, elevated background or overlapping emission limit interpretation of this class? measurement
Flare evolution and observation state Tracks how the event develops and how confidently its temporal behaviour is known.
An agent needs to distinguish an evolving flare from an incomplete observation or a retrospectively revised event record.
Time profile
Records onset, peaks and decay without forcing all wavelengths into identical boundaries.
Band-specific event timing
Attach each timing estimate to its observing band, detection rule and timestamp convention.
- What are the start, peak and end times in each relevant band, and how was each boundary selected? measurement
- Are timestamps observer reception times or corrected reference times, and how are cross-platform comparisons aligned? measurement
Coverage and revision
Represents gaps, provisional conclusions and updates to the event record.
Evolution confidence
Distinguish observed rise or decay from intervals whose state is uncertain because measurements are missing or compromised.
- Which gaps, cadence limits or instrument failures could conceal onset, a stronger peak or continued emission? measurement
- What additional observation or revised data product would justify changing the event's timing, class or current state? action
Associations, effects and response Connects the flare to related solar events and location-specific consequences without collapsing distinct causal pathways.
Operational decisions require evidence about exposure and mechanism beyond the existence or class of a flare.
Associated solar events
Links the flare to independently characterised eruptions or particle events.
Qualified event associations
Record temporal and spatial association evidence while distinguishing coincidence, inferred connection and demonstrated linkage.
- Which independently identified coronal mass ejections or particle events are associated with this flare, and what evidence supports each link? provenance
- Which predicted consequences depend on an associated event rather than on the flare's radiation itself? boundary

- For the specified receiving location and interval, which observed or predicted effects are attributable to flare radiation, with what confidence? measurement
- Which monitoring or mitigation action is justified by the receiving system's documented thresholds and the available flare evidence? action

Neighbouring kinds and how to tell them apart
Recalled without web access and unsourced; every item is a lead to verify.
- Coronal mass ejection - A coronal mass ejection expels magnetized plasma into space; a flare is an atmospheric energy-release and brightening event, and either can occur without the other.
- Solar energetic particle event - This is an enhanced population of high-energy particles in interplanetary space, rather than the flare's electromagnetic brightening.
- Geomagnetic storm - A geomagnetic storm is a disturbance of Earth's magnetosphere driven by solar-wind conditions, rather than an event in the Sun's atmosphere.
- Sunspot - A sunspot is a relatively cool, magnetically concentrated photospheric region that can persist for days or longer; a flare is a transient energy release.
- Stellar flare - A solar flare is the Sun-specific instance of the broader stellar-flare phenomenon.
- Which of these neighbouring kinds and how to tell them apart hold for the sense of solar flare this model covers, and on what evidence? provenance
