Up: JHK photometry of Nova
Near-IR photometry of nova V723 Cas
undertaken during seventeen months after
outburst reveals that its emission was a
combination of pseudophotospheric and
free-free emission. No evidence of dust
formation is seen up to this stage.
Episodic mass ejections in the post-outburst
period resulted in sharp
brightness increases or flares, which were
observed in the near-IR also. The
nova lies between 2.4 - 7.6 kpc and has an absolute magnitude of
.
