Abstract: We present a result of the multi-longitude campaign on a photometric investigation of the SU UMa-type dwarf nova in the period gap, V1006 Cyg in 2023. It displayed a long-lasted standstill (a feature of Z Cam-type stars) terminated by a long outburst (a feature of IW And stars). The long outburst did not have superhumps (a feature of SS Cyg-type stars) but showed orbital 0.09837(22) d periodicity instead. Color-color diagrams indicate that layers of the disk of different temperatures contribute to the total radiation of the system. In particular, a large contribution from the innermost hot layers is detected in quiescence.
