Just over a year ago we looked at the young star (and Gaia alert object) MO Mon. It got flagged due to showing a short 1mag dimming even. Our data did show that these might be more common than the one found by Gaia.
In the figure above we show the I-band light curve of the object so far during the current observing season. And indeed, these events are frequent, but non-periodic. Currently these evens show a gradual decline in brightness over about a week, and then a quick recovery within a few days.
Note that in other years no such events are found at all, and at times the ‘shape’ of the events is different (i.e. more symmetric ingress and egress). This is certainly an interesting object to look at in detail at some point. 🙂
