The AMI Large Array robotically triggered on the Swift alerts for the Be 
X-ray Binary, Swift J0243.6+6124 (e.g. Beardmore et al., GCN 22020; 
Kennea et al., ATel 10809; Kouroubatzakis et al., ATel 10822; also has 
Fermi alerts: Briggs et al., GCN 22047) as part of the 4pisky program, 
and several follow up observations were subsequently obtained. Our 
observations at 15 GHz are tabulated below. Our upper limit on 11 Oct 
2017 (MJD 58037) is consistent with that reported by van den Eijnden et 
al. (ATel 10886).

-----------------------
MJD       Flux Density
-----------------------
58029.16  <170 uJy
58032.04  <140 uJy
58037.01  <140 uJy
58044.05  372+/-67 uJy (likely a detection)
58045.00  <300 uJy

We thank the AMI staff for scheduling these observations.More 
observations are ongoing.
