The numbers above (right) show the temperatures (in degrees C) and humidity (%) from sensors placed all around the 4-Meter Telescope. This data was taken at the time shown in bold at the top of the page.
Click on the image or an individual number for the last 12 hours worth of data from that sensor.
Or, define a date and time range (MST), and select multiple checkboxes for multiple sensor plots. Note, that selecting too many senors and/or too large of range can make it hard to get meaningful information.
Assume HUMIDITY is plotted in %Relative Humidity, even though Y-Axis lable may indicate "Deg. C".
A temperature of 99.9 indicates the sensor is not functioning properly.
