LSST + ZTF Inventory of Nuclear Transients and Supernovae

Scanning Summary - July 2026

Updated 2026-07-02 22:05 PST

Scanning Log - July 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.

Poor observability (<3 hr above airmass 2) - shown in separate table below, excluded from sample

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
