@moustakas please post the TILEID, LASTNIGHT, FIBER for that target. It doesn't appear to be in Loa which makes it all the harder to find in daily.

Apologies. Indeed, this spectrum is not in Loa. It's here--
TILEID=24088, FIBER=1411,

tt = Table(fitsio.read('/global/cfs/cdirs/desi/spectro/redux/daily/tiles/cumulative/24088/20241224/redrock-2-24088-thru20241224.fits', 'REDSHIFTS'))
tt[tt['TARGETID'] == 39633324993414892]
