S. Srivastav, S. J. Smartt (Oxford), M. D. Fulton and K. W. Smith (QUB) report on behalf of a larger collaboration:

We report follow-up photometry of AT2024eju, the possible optical counterpart (Srivastav et al., GCN 35932) of the fast X-ray transient EP240315a (Zhang et al., GCN 35931). The images were obtained with the 2m Liverpool Telescope in g, r and i bands starting on MJD 60385.848, 1.01 days following the discovery of the X-ray transient.

The transient was not detected in any of the 3 bands with the following upper limits:

MJD	Filter	Limit (AB mag)
60385.848	g	>19.55
60385.851	r	>19.72
60385.853	i	>20.02

This suggests that AT2024eju has likely faded since the ATLAS detection ~1 day ago, further follow-up observations are encouraged.
