Working with SETI Institute scientists, Unistellar’s global network of 25,000 citizen scientists will contribute data that will help advance astronomical research. Observations will take place on the following nights:
- Sunday 5th October: C/2025 A6 (Lemmon)
- Saturday 18th October: C/2025 R2 (SWAN) + C/2025 A6 (Lemmon)
- Monday 20th October: C/2025 K1 (ATLAS)
- Monday 20th October: C/2025 R2 (SWAN) Focus Night #1 (+C/2025 A6 (Lemmon))
- Tuesday 21st October: C/2025 R2 (SWAN) Focus Night #2 (+C/2025 A6 (Lemmon))
- Wednesday 22nd October: C/2025 R2 (SWAN) Focus Night #3
- Thursday 23rd October: C/2025 K1 (ATLAS)
- Monday 27th October: C/2025 A6 (Lemmon) + C/2025 K1 (ATLAS)
- Sunday 9th November: C/2025 K1 (ATLAS)
- Saturday 15th November: 3l/ATLAS (early in the morning) + C/2025 R2 (SWAN)
Three SWAN Focus Nights (Oct 20–22) during new-moon darkness and the Orionids meteor shower are particular highlights. The campaign also includes seven additional nights to observe Comet Lemmon and Comet ATLAS (K1), as well as early looks at 3I/ATLAS. All participants who submit validated data on five or more nights will earn a 10th Anniversary Citizen Scientist certificate, and their contributions will be acknowledged in the campaign report and any resulting publications.
