Tags: #<Tag:0x00007fdd7a421580>

A brief update on SSSC (Solar System Science Collaboration) happenings over the past month. A more detailed version will be sent out to the SSSC collaboration

LSST Cadence - All the submitted Cadence Notes can be found here (including the SSSC’s submitted note). The Rubin Observatory Survey Cadence Optimization Committee will have a virtual workshop, scheduled for Nov 16–17, 2021 open to the wider community to discuss in detail recommendations for the preliminary LSST cadence selected by the SCOC.

(virtual) LSST Solar System Readiness Sprint 2021 on June 22nd, 24th, and 29th - Registration has closed for the virtual Sprint. We currently have 50 attendees registered to attend. .

Template Generation in Year 1 Research Note - Our research note highlighting the need for template generation in Year 1 of the survey for time domain Solar System science and some recommendations for template generation was accepted to Research Notes of the AAS. You can find the published version here.

Revised Rubin Commissioning Schedule and Data Preview/Commissioning Data Release Schedule: Chuck Claver presented to a joint Project + Science Collaborations Chairs Call on revised Rubin Commissioning Plans. The recorded video can be found here and the slides can be downloaded from here.

Nominations for Working Group Lead Positions and Publication Coordinators - Nominations are due by June 20th

ApJS Cadence Optimization Special issue (call for peer-reviewed papers) - Further details can be found here.

Rubin-Euclid joint Solar System data products - The Solar System representatives on the joint Rubin-Euclid data products working group have drafted a report. They are also planning a virtual Q&A session on June 24th.

Rubin Observatory international in-kind Contribution Evaluation Committee (CEC) SSSC representatives change - Meg and David will be rotating off of the CEC now that the first set of in-kind contributions has been evaluated and the international agreements are being set up. Henry Hsieh (Community software/infrastructure development working group lead) and Michele Bannister ( Outer Solar System Working Group Lead) will be rotating on as primary and alternate CEC SSSC representatives respectively. Henry and Michele will help evaluate new proposed international in-kind contributions and assist with the quarterly/yearly progress monitoring of in-kind contributions relevant to the collaboration.

Updates on LSST Prompt Data Products and Solar System Processing Pipeline Development (quoted from the monthly Data Management reports): “A Difference Imaging Analysis (DIA) track was added to the Data Release Production Pipeline. It generates good-seeing templates, subtracts them from images, detects and measures DIASources, and performs forced photometry on the image differences at the centroids of Objects. These tasks are now run by default in CI (ci_hsc_gen3) and in the biweekly DRP reprocessing of precursor datasets. A pipeline for associating objects detected on difference images to known Solar System objects was also created.”
