Photometry of GOTO065054.49+593624.51 requested
Abstract:
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."
Justification:
Monitoring observations (in V or CV filters primarily) will help identify these echo outbursts if they occur, measuring their amplitude and timescale.
Requested Data Types:

Photometry Filters:
V (Johnson)
Comparison Stars:
Finder charts with comparison stars may be created using the AAVSO Variable Star Plotter (https://apps.aavso.org/vsp).
Co-Authorship
Observers are eligible for co-authorship.
Additional Observer Input:
Monitoring observations (in V or CV filters primarily) will help identify these echo outbursts if they occur, measuring their amplitude and timescale. Achieving a high cadence is not as important in the low states. 1-3 observations per night with good signal-to-noise is preferable, but going faster is highly appreciated if any re-brightenings occur, to be sensitive to any potential variability. Observations over the next few weeks (through mid-December) will be helpful charting GOTO0650’s decline from outburst.
