Three ways to contribute

Your observing desk

Mission Control checks only what it can support with published evidence. Every route ends at a real contribution workflow.

01

Naked-eye observation

Report an aurora

Compare current geomagnetic evidence with your magnetic latitude and local darkness before heading outside.

02

Small-telescope photometry

Measure an exoplanet transit

Find bright-host transits that fit tonight’s darkness, altitude, baseline, and timing-uncertainty gates.

We check

03

Eyewitness report

Document a fireball

Capture the time, direction, colour, fragmentation, and sound while the memory is still fresh.

Local observing conditions

Transparent by construction

Evidence before enthusiasm

Mission Control downgrades a claim when a feed is stale, a field is missing, or an observing gate fails. Unknown never quietly becomes “all clear.”

Computed locally

Sunlight, target altitude, magnetic latitude, and ranking all run in this tab.

Every gate is named

Cards explain what passed, what failed, and what remains uncertain.

Real handoffs

Actions lead to established NASA or partner contribution workflows.

Thresholds, limitations, and astronomy engine

Astronomy is computed in your browser with Astronomy Engine 2.1.19. Transit photometry requires the sun to be at least 12° below the horizon; aurora uses 6°. Aurora bands are plausibility estimates, not a local forecast: cloud, light pollution, and the direction of the auroral oval remain unknown.
