The First Detection of an Orphan Burst at the Rise Phase

We report on the earliest detection of the optical transient MASTER OT J123248.62-012924.5 coincident within the error box with the optical and X-ray transient AT2021lfa/ZTF21aayokph. In our images the brightness of the object rises monotonically with confidence. We interpret this transient as a gam...
