This is the observation of AT2026zzz

RA DEC = 04:00:00 10:00:00.00

seeing<1.5
AM<1.6
Moon dark
sky: cirrus

LBC
===

we need for LBC ugrz imaging , 36min per filter 
!!!
please repeat the observation to reach 1 hour per filter
!!!
the copoint is included

MODS
====

1) We ask for 1 hours of spectra in dual grating, slit 1.2"
Please take care of the UV flux in the slit. My features are below 4000 AA

2) ugrz dual imaging is added too (with dithers) , about 16/20min per filter :
2x2min*4 offsets in grz
1x5min*4 offsets in u

3)
A second observation  in blind offset is added (folder blind) from a R~17mag star is added, for when the source itself is too faint for acquisition.
In this case please keep we fixed the PA=341.75deg so both the star source and target stay in the slit, even after the blind offset (to center on the star).
We do this to facilitate combining the spectra (a ABBA offset pattern is used for removing skylines and other internal fake features).

!!! The current PA keeps the flux below 4500AA in the slit for -2<HA<1 !!! follwing https://cgi.astronomy.osu.edu/MODS/ObsTools/obstools.html
Since ofr our science we are interested in lambda<4500, when observing outside this range we need to change the PA and possibly 
find another star to be placed in the slit.
!!!

4)
an example of MODS-MOS mask is added for reference

LUCI
===

1)
we ask for imaging JHKs filter, 1 hour total exp time per filter

2)
we also ask for zJ200 and zJ200 spectra with 1" longslit
1 hour in total for each filter (180s x10 offset per each LUCI)

3)
a K210 spectroscopic observation in blind offset is prepared for when the source is faint:
blind offset from a J=15 Vega bright star

We ask for a total exposure of 72min:
12 offsets (2 ABBA) x 180sec = 36min per LUCI, 

Note: we keep the star in the slit with PA=9.98deg  to failitate staking after sky removal
