AT 2023gde was reported to TNS as a possible nova by De and Hankins on behalf of the Palomar
Gattini-IR collaboration and the discovery and spectroscopic classification as a highly reddened Galactic classical nova was reported
in ATel #15993. In Atel #15994 we reported an accurate optical position and photometry in the r', i' and zs bands using the Las Cumbres
Observatory global telescope network (LCOGT). Here, we report that the nova has also been detected by ZTF (ZTF23aafailn) and in ATLAS forced photometry.
The transient was first detected by ZTF on UT 2023-04-11 10:41:32, with r = 17.84 +/- 0.06. The nova was not detected by ZTF
on UT 2023-04-08 11:52:45 with g-band limiting magnitude of 19.68 and on UT 2023-04-08 11:05:27 with r-band limiting magnitude of 19.95.
We have extracted ATLAS forced photometry at the LCOGT i'-band position given in ATel #15994, that shows first detections on UT 2023-04-11 in the
ATLAS orange filter and additional detections after maximum light.
The ZTF photometry is available at the ZTF/LSST brokers
ATLAS forced photometry is available here.
