Early Release Data available
XRISM Early Release data are available for those considering submitting a proposal for the XRISM Cycle-1 G uest Observation program. The data include X-ray images and spectra obtained during the commissioning or calibration operations of the instruments aboard XRISM, the Resolve and Xtend. The data are in the FITS format, widely used in the field of astronomy. The first data release is Perseus cluster core: Resolve spectrum. Note that the ER data are not yet fully calibrated and corrected but are released on a trial basis for reference purposes in proposing observations. Do not use this data for scientific research.

1-day XRISM workshop in Leiden, February 15 2024
The Space Research Organisation of The Netherlands (SRON) is organising a one-day workshop on proposal discussion and preparation on February 15th 2024, 10:30-17h at SRON-Leiden. The workshop will focus on proposals for the European share of the XRISM exposure time and offers an online (Zoom) morning info session and two in-person hands-on sessions in the afternoon on point sources and extended sources, respectively.

First Announcement of Opportunity
After successful launch of XRISM on September 7, 2023 and successful critical operation period, the first announcement of opportunity opens November 15, 2023.
In consideration of ESA’s contribution to XRISM, not less than 8% of the total Guest Observing Time, or an equivalent return as mutually agreed, shall be allocated to ESA. The ESA Director of Science has thus issued the invitation to submit Guest Observer proposals for the observation period between July 2024 and June 2025: Letter by ESA Director of Science
Please find all instructions in this document: Announcement of Opportunity for the XRISM GO program
The due date for proposals is 12:30 CET, 22 February 2024
Target for the publication of the POG and the opening of the ARK/RPS: 7 December 2024

Resolve Operational Temperature reached
After reaching the required operational temperature in the Resolve dewar, the adiabatic demagnetization magnetic refrigerators (ADR) were activated, and the target temperature of 0.050 K for the array stage was achieved.
The full array of detector pixels successfully detected X-rays from the calibration source on the Filter Wheel and showed excellent uniformity, with better than 5 eV energy resolution.
Now, the Xtend system is being activated.

P.S. The launch time to second precision is driven by the SLIM moonlander being launched on the same vehicle. It requires second-precision launch to get on the right path to the moon. There is only one 1-s launch slot a day, so either it is this time or next day.......
