The erupting object ASASSN-16dt has finally shown clear and constant superhumps
with an amplitude range of more than 0.1mag. This seems to have occurred now
during a rebrightening phase.
The initial outburst was detected by the ASASSN instrumentation on 1 April, but
the object didn't show much light modulation until now, 25 days later. However
there might be doubt about that as there has been an observing gap of a week
centered around 19 April. 

Observations of 26.9 April at CBA Kleinkaroo showed ASASSN-16dt around magnitude
13.6. The superhump period (Peranso/Clean) derived from the 7h observing run was
0.0647d.
