The 2025 Catalina Sky Survey Monsoon Workshop will be held in Tucson, August 1-5, as a splinter session of the ADASSx Summer Software Workshop, immediately following the Rubin Community Workshop.
Registration (free) and abstract submission are now open.

A well-written piece on Planetary Defense featuring a rock found at CSS in The American Scholar. Enjoy! π

The recurrence interval for a 140m+ impact is thousands of years. The idea is to catalog them all so we can be sure when the next impact might happen.

Their orbits tend to be more gravitationally dynamic though, they can evolve into new orbits which might pose a threat in the future so they get closer attention.

2025 CE13 is a newly discovered potentially hazardous asteroid. It is between 141-316m in diameter and passes within 4.4LD of Earth's orbit. It was discovered on Feb 2nd, 2025 by CSS observer H. Groeller. 2025 CE13 poses no impact threat to Earth. π

Congratulations to CSS observer Hannes Groeller. Hannes recently discovered comet C/2025 D1 (Groeller) from the Bok telescope, which we operate under a partnership with Spacewatch. C/2025 D1 has the largest perihelion distance of any comet found to date. Interactive orbit in comments. π

2025 CW is a newly discovered potentially hazardous asteroid. It is between 200-450m in diameter and passes within 4.32LD of Earth's orbit. It was discovered on Feb 3rd, 2025 by CSS observer T. Beuden. 2025 CW poses no impact threat to Earth. π
