NEOWISE Reactivation 2024 Data Release

The NEOWISE Reactivation 2024 Data Release adds approximately 2.5 million image sets and 18.4 billion source detections to the public archive. These data were acquired during the tenth year of the NEOWISE Reactivation Mission, 13 December 2022 to 13 December 2023. When combined with the data from years 1-9, the NEOWISE-R database contains approximately 25.3 million sets of 3.4 and 4.6 micron images and 189 billion source detections extracted from those images.

IRSA Viewer Update

A new version of IRSA Viewer and related tools has been released. Changes include drag and drop file uploads, improved property sheet features, saving catalogs as SAO Image DS9 regions files, and easier access to data documentation from DCE results pages.

The twentieth public data release from the Zwicky Transient Facility contains approximately 53.5 million images, 828 billion source detections extracted from these images, and 4.75 billion light curves.

IC417 Data Release

A catalog of YSO candidates in IC 417 is now available. This contributed data product is the result of work conducted as part of the NASA/IPAC Teacher Archive Research Program (NITARP).

2024B NASA IRTF Call for Proposals

The Call for Proposals to use the NASA Infrared Telescope Facility (IRTF) in the 2024B semester (August 1, 2024 to January 31, 2025) is live. Proposals may be submitted through the online submission form until 5:00PM on April 01, 2024 HST. Available instruments include: SpeX, MORIS, iSHELL, MIRSI/MOC, and ‘Opihi. Many IRTF observations can be found in the IRTF Archive at IRSA and we encourage proposers to check for their targets in the archive.
