Lightcurve and Rotation Period of Binary Asteroid (1727) Mette
Minor Planet Bulletin, 53(4), 269–270.

Eleven nights of R-band photometry (March–April 2026) of the binary Hungaria asteroid (1727) Mette give a synodic rotation period of 2.9810 ± 0.0004 h and an amplitude of 0.26 mag (minimum axis ratio a/b ≥ 1.27). After removing the primary lightcurve, no mutual events from the known satellite were seen above the noise, consistent with a more pole-on viewing geometry at this apparition.

Lightcurve and Rotation Period of (3409) Abramov
Minor Planet Bulletin, 53(4), 277–278.

Four nights of R-band photometry (September 2025) of the Koronis-family asteroid (3409) Abramov give a synodic rotation period of 8.505 ± 0.001 h and an amplitude of 0.49 mag, implying a moderately elongated shape (a/b ≥ 1.57). The period differs from the 7.791 h previously reported; phasing the 2025 data to that value does not produce a coherent lightcurve.

Building My Remote Observatory at 15: Engineering for Millimagnitude Photometric Precision
Journal of the Royal Astronomical Society of Canada, 120(4), 135–141. Feature article.

A practical account of designing, funding, configuring, and calibrating a remote research observatory (IAU Minor Planet Center code R60) at a dark-sky site in Nerpio, Spain, engineered to reach millimagnitude photometric precision for asteroid and exoplanet time-series work. It covers instrument selection, guiding and flat-fielding strategy, and the calibration pipeline that makes the data science-grade.

Photometric Characterization of Newly Discovered Potentially Hazardous Asteroid 2025 FA22
Journal of the Royal Astronomical Society of Canada, 120(2), 50–53.

Multi-band CCD photometry of potentially hazardous asteroid 2025 FA22 during its September 2025 close approach gives a synodic rotation period near 13.1 hours and BVRI colour indices consistent with an S-complex (stony) classification, characterising a potentially hazardous near-Earth asteroid within days of its close approach, six months after its discovery.

Lightcurve and Rotation Period of 2025 FA22
Minor Planet Bulletin, 53(2), 129.

Six nights of photometry of the newly discovered potentially hazardous asteroid 2025 FA22 yield a synodic rotation period of 13.075 hours. The lightcurve amplitude indicates an elongated shape, characterising the object's spin and figure during its close approach to Earth. This was the first published rotation period for 2025 FA22, and it has since been cited by other studies of the object.

Developing algorithms to determine an asteroid's physical properties and the success of deflection missions
Acta Astronautica, 220, 62–74.

Open-source Python algorithms derive asteroid rotation periods, diameters, and binary mutual-orbit periods from a combination of sparse and dense photometry. Applied to the Didymos system, the method recovers the DART-induced shortening of Dimorphos's mutual orbital period from 11.91 to 11.34 hours, independently confirming the spacecraft's deflection of the asteroid.

Finding unknown asteroids to strengthen planetary defense
Journal of the Royal Astronomical Society of Canada, 117(1), 28–30. Research note.

A reproducible Python pipeline detects previously uncatalogued moving objects in open survey images by aligning image sequences and isolating sources that shift against the fixed background stars. A masking step suppresses contaminating light to reveal faint asteroid candidates, yielding position-versus-time astrometry suitable for follow-up and reporting.
