The submission of proposals in response to SC107 can take place, initially, any time from April 1st to September 1st, 2021.The recommended maximum requested time is 25 hours.The applicants must indicate the class to which the proposal belongs.They must comply to the proposal anonymization rules: proposals violating the requirements will be flagged by the reviewers to ESO for possible disqualification.Proposals qualifying for SC107 must be prepared with the p1 proposal submission tool, as for regular cycles.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.

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). SC107 will be open as of April 1st, 2021. It is therefore expected that only very highly rated proposals may obtain observing time. convincingly justify why the observations must be carried out in P107 in the Special Call Justification field.ĭue 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.clearly indicate in the proposal Title field which of the three criteria described above applies ( see below).preferably request no more than 25 hours of total execution time.Proposals submitted in response to SC107 should: SCTYPE-F: proposals asking for follow-up observations of a programme recently conductedfrom ground-based and/or space telescope facilities, where rapid implementation holds the promise of breakthrough results.SCTYPE-R: proposals of a risky nature, requiring a small amount of observing time to test the feasibility of a programme.SCTYPE-C: proposals concerning a highly compelling and competitive scientific topic, requiring urgent observations.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. 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).
