Proposal #571

Good morning, I'm Sauro Gaudenzi, my observer code is GSAD, in support of the AAVSO alert nr 877 I ask for the use of a telescope to observe the GOTO0650 dwarf nova, I ask that at least one observation be made per week with V filter, 60 shots of 60 seconds until December 15th. Dr. Thomas Killestein (Univ. of Turku) requests photometry of GOTO065054.4 (Lyn). He writes: "GOTO0650 is a dwarf nova (DN) discovered by citizen scientists working as part of the Kilonova Seekers (https://kilonova-seekers.org) project, which invites members of the public to inspect data from the Gravitational-wave Optical Transient Observer (GOTO, https://goto-observatory.org/). The object was discovered <2d from outburst, and has been the subject of an intensive follow-up campaign. We've been following this DN outburst with GOTO for the past month or so, and AAVSO data have already been very useful in constraining an initial dip, and tracing the evolution of superhumps. GOTO0650 entered into a deep dip (currently around 19th magnitude), but these objects often show "echo outbursts" where they rapidly rise and decline in brightness on timescales of days, with multiple of these happening before the object finally settles down into the final decline, telling us about the disk state." Monitoring observations (in V or CV filters primarily) will help identify these echo outbursts if they occur, measuring their amplitude and timescale. I would really like these observations as I am a citizen scientist collaborating on the Kilonova Seekers project through the www.zooniverse.org platform
