The ESO research studentship programme provides an outstanding opportunity for PhD students to experience the exciting scientific environment at one of the world's leading observatories. ESO's studentship positions are open to students enrolled in a university PhD programme in astronomy or related fields. Students accepted into the programme work on their doctoral project under the formal supervision of their home university, but they come to ESO to work and study under the co-supervision of an ESO staff astronomer for a period of between one and two years.

The deadline for proposal submission for Period 103 (1 April 2019 - 30 September 2019) was 27 September, 2018. 914 valid proposals were submitted, including 20 Large Programmes, of which one is a GTO Large Programme. The number of proposals for Period 103 is very similar to that of Periods 91 (893), 92 (892), 93 (898), 94 (901), 98 (901), 99 (887), 100 (895), 101 (899) and 102 (916) so the plateau observed since peaks in Periods 95 (934), 96 (960) and 97 (1024) remains. On the VLT the most requested ESO instrument was X-shooter with 258 nights, followed by MUSE with 226 nights, and FORS2 with 145 nights. HARPS on the ESO 3.6-metre was the most demanded instrument at La Silla, with a request of 190 nights, though the combined request on the NTT was larger (246 nights).

The response to our call for volunteers for the Distributed Peer Review (DPR) experiment was very enthusiastic, well beyond our original expectations. Out of the 272 scientists that had initially expressed their interest, 172 (63%) submitted a proposal for Period 103 as Principal Investigators (PIs) and will hence serve as reviewers. This corresponds to about 23% of all PIs in Period 103. This is also a reminder that the DPR process will run in parallel to the regular proposal review by the Observing Programmes Committee and will have no effect on the final ranking of the proposals.

ESO wishes to warmly thank its community for the enthusiastic response and collaborative spirit, which will ensure the success of the experiment! An in-depth analysis of the experiment and its results will be presented in due course.

The latest edition of ESO's quarterly journal, The Messenger, is now available online. In issue 173 you will find information about Service Mode and Visitor Mode at Paranal, as well as new plans for proposal submission and selection. This issue also contains several articles presenting science highlights from ESO and ALMA facilities, news from ESO fellows and students, reports from workshops, and a tribute to Leon Lucy.

4MOST is a state-of-the-art, high-multiplex, optical spectroscopic survey facility currently under construction for ESO’s 4-metre VISTA telescope. During the first five years of operations 4MOST will be used to execute a comprehensive programme of both Galactic and extragalactic Public Surveys, and 30% of the observing time during this period will be available to the community. The process of selecting Community Public Surveys will be initiated by a Call for Letters of Intent for Public Spectroscopic Surveys, to be issued by ESO in mid-2019. In preparation of this Call, ESO and the 4MOST Consortium are jointly organising a workshop to prepare the ESO community for this exciting scientific opportunity, to assist potential PIs in successfully responding to the Call, and to foster scientific collaborations between the community and the 4MOST Consortium.
