DDT - Discretionary Time



To allow for more flexibility in the use of LBT, the policy of INAF Discretionary Time was estabilished in 2012. In addition to the present call, observations can be requested at any time during the year in the case of:

  • Proposals requiring the immediate observation of a sudden and unexpected astronomical event;

  • New, unforeseen proposals requesting urgent observations on a hot and highly competitive scientific topic;

  • Proposals asking for follow-up observations of a program recently conducted from ground-based and/or space facilities, where a quick implementation should provide break-through results;

  • Proposals of a somewhat risky nature requesting a small amount of observing time to test the feasibility of new observing capabilities.


  • Users interested in these INAF-DT projects must send the DDT Form (doc, LaTeX) to LBT Team ( lbt-italia@inaf.it).
