Tools: get_stargazing_conditions get_tonight_agenda find_dark_sky_sites get_aurora_forecast get_light_pollution
get_stargazing_conditions | Score the next nights for stargazing at a location (0-100 per night).
Use for "when should I stargaze this week near X", "is Saturday any good
for the Milky Way", trip planning. Each night combines the three-layer
cloud-cover forecast, moon illumination and up-fraction, and the
astronomical-darkness window; `best_window` names the best upcoming night.
Also returns the location params: lat*, lon*, nights |
get_tonight_agenda | Get tonight's stargazing plan for a location: score, darkness window, and what to observe.
Use when the user asks "what can I see tonight" / "is tonight worth going
out". Returns tonight's sky score and darkness window plus a ranked agenda
of observing targets appropriate for the location's sky darkness.
Args:
lat: Latitude in decimal degrees (-90..90).
lon: Longi params: lat*, lon* |
find_dark_sky_sites | Recommend dark-sky sites near a location, ranked by whether the drive is worth it.
Use for "where should I drive to stargaze near X". Sites are grouped by
drivability (how far), then ranked by a drive-worth score combining the
best weather window over the next 7 nights, how much darker the site is
than the user's location, and drive time. Drive times are approximate
(straight- params: lat*, lon*, limit |
get_aurora_forecast | Get the aurora (northern/southern lights) outlook for a location.
Use for "any chance of aurora tonight near X". Combines the Kp-index
forecast with the location's geomagnetic latitude to say whether aurora
could be visible there, and when.
Args:
lat: Latitude in decimal degrees (-90..90).
lon: Longitude in decimal degrees (-180..180).
Returns {kp_forecast:[{ params: lat*, lon* |
get_light_pollution | Estimate light pollution at any point: approximate Bortle class and what's visible there.
Use for "how dark is the sky at X" / "can I see the Milky Way from X".
Returns the zenith-brightness-derived estimate (mpsas, approximate Bortle
class) and a plain-language ceiling: what the Milky Way, naked-eye and
telescope views are like under that sky. This is a satellite-data estimate,
