NJAA utilizes Foster Systems Astro Alert Weather Monitoring System that provides our members and community with the following weather related data at the observatory.

- Precipitation (rain or snow) detection.
- Ambient light awareness (Day, Dim, Darkness pending).
- Ambient outside temperature/humidity/dew point.
- Anemometer to measure wind speed.
- Infrared sky temperature measurement, which is the most reliable measure of impending precipitation. When clouds gather the sky temperature rises, indicating rain may not be far behind
