Dear observers,
I am writing to request photometric follow-up observations of a new large-amplitude outburst, likely a dwarf nova: TCP J00560713+4301406.
This object was discovered at CV=12.2 mag on 2026 06 01.4 UTC.
ATLAS also detected this outburst on 2026 05 31.6 UTC around 15.1 mag (o band),
likely on the rise.
I observed this object on its decrease on the nights of 2026 06 07.07 UT, 2026 06 08.06 UT and 2026 06 09.06 UT with a Seestar S50. The last magnitude I measured are V=14.0 and R=13.85 on 2026 06 09.06 UT.
The target and the observations have been added to BHTOM.
Further short-cadence photometric observations covering 0.1 d to confirm the nature of this object are encouraged.
With best regards,
Weronika Skrobacz
