LSST + ZTF Inventory of Nuclear Transients and Supernovae

Scanning Summary - September 2026

Scanning Log - September 2026

Data

ZTF/LSST ID - Sources are cross-matched between surveys by cone-searching at the position of the latest alert; each source carries an ID for every survey in which it has been detected.

Peak, first & last - All photometric statistics are derived from the combined ZTF + LSST light curve. The listed filter and survey identify the specific detection from which each value was measured.

Data source - Photometry, spectroscopic classifications, host redshifts, and follow-up status are retrieved from Fritz, the LIONS group alert marshal.

Magnitude trend (mLast)

↑ Getting brighter: magnitude decreased vs. previous detection (>1 d ago, same filter)
↓ Getting fainter: magnitude increased vs. previous detection (>1 d ago, same filter)
↑ First detection in this filter band
↓ Latest point is a non-detection
