Proposal

RZ Piscium usually clasified as an UXOr it's rather a variable of its own type. Its brightnes, normally of 11.5 mag. is occasionally dimmed for a short time (a few days) by 1 - 3 mag. There are some hints, that deepest dips may appear periodically. Although it was thouroughly studied many times (e.g. G.M. Kennedy et al. 2016 R. Soc. open sci. 4:160652 and references therein), the cause for those dimmings remains unclear. Moreover, it seems that so far this year the star has never returned to its normal brightness.
I've been observing this object visually, but I cannot do it as often as needed to clear up the situation.

Requested filters: B, V, R, I
Magnitude range: 11 - 14.5 (V)
Cadence: once per day
Number of exposures per run: 1 per filter
Start date: asap
End date: as long as accessible (mid of March 2024)

Use of data: Submitting to AAVSO Database after VPhot analysis
