New & Updated HLSPs for August

New:

• The Olin Wilson Legacy Survey (OWLS; Morris et al 2025) presents spectroscopic observations from a planned 10 year survey of Ca II H & K emission, using observations made with the ARC 3.5m Telescope at Apache Point Observatory. The primary goal of the survey is to investigate activity cycles in low mass stars. The sample includes stars chosen from the legacy Mount Wilson survey carried out by Olin Wilson more than 50 years ago, together with newly identified planet-host stars and a select sample of early-mid M dwarfs. This collection of spectral time-series presents the first four years of data, with more than 1037 observations of 270 stars, with a specific focus on K and M stars.  The team identifies a subsample of 153 stars for continuing observations over the full 10 year survey. The ultimate goal is to link the activity cycle and rotation periods in a robust sample of stars spanning FGKM spectral types and to investigate the implications for the underlying magnetic dynamo.  View OWLS collection page >

Updated:

• OPAL added HST observations of Neptune Cycle 31 from June 2025, which are now available at MAST.
• QLP calibrated light curves from TESS full frame images for Sector 93 are now available at MAST. This Sector adds 2,185,816 targets derived from 200 second cadence FFIs.
• TESS-SPOC calibrated light curves and target pixel files from TESS full frame images for Sector 77 are now available at MAST. This Sector adds 160,000 targets derived from 200 second cadence FFIs.
• TICA updates this month include the last set of calibrated TESS full frame images from Sector 94, as well as all data from Sector 95.
