Daily Sunwatch uses scientific and government resources to follow the Sun, space weather, the Moon, and terrestrial weather. This page highlights the primary resources that support Sunny’s observations.
Each title links to an official resource.
Data, imagery, forecasts, and model guidance remain the work of their respective providers.
The primary scientific resources that help Sunny keep an eye on things.
Operational U.S. space-weather observations, forecasts, alerts, and imagery.
NOAA SWPC is one of Daily Sunwatch's primary operational sources, providing much of the real-time context behind Sunny's solar, solar-wind, geomagnetic, aurora, and coronagraph observations.
Near-continuous, multi-wavelength observations of the Sun.
NASA's Solar Dynamics Observatory provides high-resolution solar imagery used throughout Daily Sunwatch for routine observations, flare context, multi-wavelength views, and visual analysis.
NASA's space-weather event database and notification resource.
DONKI provides event information and scientific context for activity such as solar flares and coronal mass ejections, helping Sunny connect observations to reported space-weather events.
Physics-based modeling of the solar wind and CME propagation through the inner heliosphere.
Daily Sunwatch uses WSA–ENLIL model guidance for additional context when evaluating how reported CME events may propagate through interplanetary space and toward Earth.
Official astronomical data from the U.S. Naval Observatory.
Daily Sunwatch uses USNO astronomical data to support its nighttime content, providing lunar phase, illumination, and upcoming phase information.
High-precision solar system ephemerides and astronomical position data.
NASA/JPL Horizons provides astronomical position data used by Moony Moonwatch to determine the Moon's current constellation, based on its position among the official astronomical constellation boundaries.
NASA Goddard scientific visualizations and imagery.
NASA SVS provides lunar visualization imagery used in Daily Sunwatch's nighttime content, complementing astronomical information from the U.S. Naval Observatory.
Official U.S. terrestrial weather forecasts and observations.
The National Weather Service provides terrestrial weather information for Daily Sunwatch's occasional East Coast weather observations.
An optional supporting layer for selected imagery, kept separate from Sunny's official scientific data sources.
Optional AI-assisted visual analysis for selected solar imagery.
Sunny Vision helps Daily Sunwatch examine selected imagery for potentially notable visible features and add short observational context when appropriate. It is supplementary rather than authoritative, and official scientific observations and model guidance remain separate.
Daily Sunwatch is an independent project and is not affiliated with, sponsored by, or endorsed by NOAA, NASA, the U.S. Naval Observatory, the National Weather Service, or OpenAI.
