Observations of last night


The latest measurements can be downloaded in text format using this page. This lists all sensors in coma seperated format (csv), in the following order: Date, bay temperature, spectrograph temperature, electronics room temperature, optical bench temperature, outside temperature, bay humidity, spectrograph humidity, electronics room humidity, outside humidity, solar height, pressure, wind speed, peak windspeed, wind direction, windspeed insdide the bay, brightness, rain, weather good?, dust, Living room temperature, laboratory temperature, oiltemperature telescope 1, oil temperature telescope 2.
If the observing conditions are deemed good, values marked as green, otherwise as red. The rain sensor reads 0 for no rain, 2 for constant rain detection on both sensors, values in between for mixed conditions. The newest webcam image is shown in the top left position, new images are taken a few minutes before and after opening/closing, about one hour before sunset, one hour after sunrise, and at noon.
