*: When real time measurements are available (green line) the forecast at short time scale (red or magenta line) is available too, provided it exists at least one more night in the last five nights with observations (condition to apply the AR method). See legend for more details. We remember that the DIMM is located inside the LBT dome. That means that, if the LBT dome is closed for whatever reason including bad weather, we have no real-time seeing measurements and, as a consequence, we have no forecast at short time scale of the seeing.
