Re: ASASSN-25dc; start of the rapid fading from the outburst

Our observations with Lesedi telescope at SAAO detected the start of the rapid fading from the outburst on 2025-08-12. The current brightness is 14.5 mag, and further fading is expected.
Considering its long plateau duration, superhumps after 2025-07-25 are likely stage B superhump. 

Further snapshosts are still encounraged as this system might go some rebrightening outbursts.

Best regards,
Yusuke
