Rubin Observatory is still in an early operations phase.
The key objective is to improve the image quality and survey efficiency in order to start the ten-year LSST survey. The amount of science-grade data collected during this early phase will vary. For the general timeline during this phase, read more about the Early Science Program.
All observations were obtained with the LSST Camera (LSSTCam). Find a description, key numbers, filter bandpasses, and more in the LSSTCam documentation.
A live dashboard showing alert processing over the last twelve hours is available at ls.st/alert-stream-status.
Information about the strategy and cadence for the Legacy Survey of Space and Time can be found at survey-strategy.lsst.io.
The projected Rubin schedule can be obtained via ObsLocTAP with the browser-based static viewer or all-sky map interface, and programmatically as demonstrated in the Commissioning :ref:`tutorials <tutorials-notebook>`.
Automated per-night reports are publicly available as scheduler viewer reports. Static files of LSSTCam visits metadata are available in the Commissioning :ref:`tutorials <tutorials-notebook>`. In the future, observational metadata will be available as queryable tables and documented under :doc:`/products/index`.
During early Alert Production, templates (and thus alerts) primarily exist in the Deep Drilling Fields.
As of February 2026, templates had been deployed in Alert Production for the fields listed in the table below. All of these are DDFs except the M49 (Virgo) field, which was part of the Rubin First Look images.
| Name | Coordinates | Filters |
|---|---|---|
| COSMOS | 150.11, 2.23 | ugrizy |
| ECDFS | 52.98, -28.12 deg | riz |
| ELAIS-S1 | 9.45, -44.02 deg | griz |
| EDFS_a | 58.9, -49.32 deg | griz |
| EDFS_b | 63.6, -47.6 deg | griz |
| XMM-LSS | 35.57, -4.82 deg | iz |
| M49 (Virgo) | 187.4, +8 deg | ugri |
Additional template images will be generated incrementally during the early science phase, and information about template regions will be added here. Details are available in :doc:`/processing/templates/index`.

Tools for visualizing the current template holdings are under development.
