VVVX DR1.1 Published: Releasing the Entire Ks Time Series

Published: 20 Oct 2021

The VISTA Cycle 2 ESO Public Survey project -VVV eXtended- PI D. Minniti, P. Lucas, is carried out with VIRCAM on VISTA in the JHKs filters and covers a total of ~1540 deg2 of the southern Galactic plane. The VVVX DR1.1 complements DR1 by mainly providing i) the missing Ks time series and ii) the source lists generated from the pawprints published in DR1, which were observed between July 2016 and March 2018. The released data total about 9 TB. Science products generated from observations in the time interval from April 2018 to October 2019 are accessible in the already published DR2 release.

APEX Heterodyne Line Intensity Monitoring Is Now Online

Published: 15 Oct 2021

A new interactive Grafana dashboard has made publicly available with the relevant results of the line intensity monitoring program, part of the APEX observatory calibration plan. An automated data reduction pipeline has recently been developed by the APEX Sciops team to analyse the scans of reference CO and HCN transitions in pointing sources. This new interface allows PIs to access the database with all these calibration observations, irrespectively of which specific project the observation was taken on.

ESO Period 109 Proposal Submission Statistics

Published: 15 Oct 2021

The deadline for proposal submission for Period 109 (1 April 2022 - 30 September 2022) was 23 September, 2021. The number of submitted proposals for Period 109 was 878, similar to that in previous Periods, so the plateau in the number of submitted proposals observed since several years remains. On the VLT the most requested instrument was MUSE with 255 requested nights, followed by X-Shooter with 252 nights, UVES (138n), ESPRESSO-1UT (132n) and CRIRES (122n). HARPS on the 3.6-metre telescope was the most demanded instrument at La Silla, with a request of 154 nights.
