Cycle 27 massive stars (Summer 2020+)
Massive stars in the LMC/SMC are being observed under program IDs 16090 through 16103. See the target Large Magellanic Cloud and Small Magellanic Cloud tables for the most up-to-date HST plan windows.
Deliveries JUL 2020
The inaugural launch of this website, the new home for the ULLYSES program. Here you can find scheduling information and target tables. In the future, additional tools will be provided for investigating and downloading ULLYSES data products.
Pre-imaging observations (Summer 2020+)
High mass stars in Sextans A and NGC 3109 will have pre-imaging observations taken with WFC3/F225W to refine our knowledge of the UV flux and better plan spectroscopic observations.
Anticipated Deliveries SEP 2020
The first release of ULLYSES co-added datasets, including newly obtained observations from Cycle 27. Data released are expected to be COS and STIS co-adds only. This data release will be accompanied by the first release of the Quicklook tool on the website.
LCOGT Pilot program begins (Fall 2020)
A pilot program will obtain u', V, and Iband high cadence imaging with the Las Cumbres Observatory Global Telescope (LCOGT) for the 13 T Tauri stars in the Orion OB1 association and the σ Orionis cluster and two of the T Tauri Monitoring stars, RU Lup and TW Hya.
Cycle 28 survey stars (NOV 2020+)
Continuing observations of massive stars in the LMC and SMC and beginning observations of stars in Sextans A and NGC 3109. Beginning observations of T Tauri stars. Stars prioritized for Cycle 28 are those with TESS coverage overlapping Cycle 28, including the 13 T Tauri stars in the Orion OB1 association and the σ Orionis cluster. The Orion observations will occur between 19-Nov-2020 and 17-Dec-2020 to be simultaneous with TESS.

First epoch of low mass monitoring stars (Spring 2021+)
The set of four T Tauri monitoring stars (TW Hya, RU Lup, GM Aur, and BP Tau) will each be observed four times per rotation period over three rotation cycles. The first epoch of TW Hya will occur simultaneously with TESS sometime between 07-Mar-2021 and 02-Apr-2021. The first epoch of RU Lup will occur sometime in May or June 2021.

Quarterly data release.
Second epoch of low mass monitoring stars (JAN 2022+)
A second epoch of observations will be obtained for each of the four T Tauri monitoring stars, occurring 9-12 months after the first epoch. These epochs will again be a set of four observations per rotation period for three rotation cycles.
