[vsnet-alert 24701] Re: MASTER OT J172758.09+380021.5 superoutburst

[Tonny Vanmunster tonny.vanmunster@gmail.com via vsnet-alert]

Note that superhumps in MASTER OT J172758.09+380021.5 were actually seen on
multiple nights in 2018 (Jul 22/23, Jul 23/24, Jul 24/25) and in 2019 (Apr
21/22 by two different observers, Apr 22/23, Oct 08/09, Oct 09/10) and by
multiple observers (Lew Cook, Jesse Leahy-McGregor, myself), as one can
derive from the AAVSO International database. Additional observations
evidently are always useful.

Best regards
Tonny
