Following the suspension of the regular Call for Proposals for ESO Period 107 due to the ongoing COVID-19 pandemic, and as previously announced, ESO is issuing a Special Call (hereafter SC107) for the submission of projects consisting of novel and urgent observations that must be executed during P107 (April 1st - September 30th, 2021).
The spirit of SC107 is to offer ESO's community the opportunity to take the lead on (or to maintain its leadership) on new, important scientific cases, without having to miss out on them because of the pandemic.
SC107 will be open only to:
- SCTYPE-C: proposals concerning a highly compelling and competitive scientific topic, requiring urgent observations;
- SCTYPE-R: proposals of a risky nature, requiring a small amount of observing time to test the feasibility of a programme;
- SCTYPE-F: proposals asking for follow-up observations of a programme recently conducted from ground-based and/or space telescope facilities, where rapid implementation holds the promise of breakthrough results.
Proposals submitted in response to SC107 should:
- preferably request no more than 25 hours of total execution time;
- clearly indicate in the Special Remarks field which of the criteria described above apply (see below);
- convincingly justify why the observations must be carried out in P107 in the Special Call Justification field.
Due to the considerable amount of time already committed in Period 107 to Large Programmes and other high-priority programmes that could not be executed during Periods 105 and 106, only up to 15% of the time dedicated to science observations in Period 107 will be available through SC107. It is therefore expected that only very highly rated proposals may obtain observing time.
SC107 will be open as of April 1st, 2021. Users will be able to submit proposals any time and only for observations that must be carried out during P107 (April 1st - September 30th, 2021). Requests for Period 108 and subsequent semesters must be submitted through the regular channels, whereas requests for transient events must be submitted through the DDT channel.
