V1159 Ori coverage needed to monitor for outburst to trigger radio observation
Abstract:
Dr. Christian Knigge (University of Southampton) requests coverage of V1159 Ori, an ER UMa-type cataclysmic variable (a subtype of SU UMa CVs), from now through 2025 April 15. A radio observation is needed urgently, and this can only be triggered when the system is in outburst. Thus, it is essential to know when an outburst occurs. Coverage in V is requested; CMOS/DSLR observations are also welcome, as are CV and visual.
Justification:
Knowledge of the state of V1159 Ori - quiescence or in outburst - is essential to be able to trigger a request for radio observations, which are urgently needed for research purposes. Observations provided by the AAVSO observers will provide this essential knowledge.
Requested Data Types:
Photometry
Targets
| Name | Magnitude | Variability Type | Photometry Notes | Spectroscopy Notes |
|---|---|---|---|---|

Spectroscopy Lines:
No spectroscopy lines provided
Photometry Filters:
V (Johnson)
Comparison Stars:
Finder charts with comparison stars may be created using the AAVSO Variable Star Plotter (VSP, https://apps.aavso.org/vsp/).
Co-Authorship
Observers are not eligible for co-authorship.
Additional Observer Input:
One to a few observations per night are requested. V is preferred; CMOS/DSLR (TG) and CV are also valuable. Visual observations are also welcome. Please submit your observations promptly, especially if an outburst is detected. V1159 Ori is typically around 14.9-15.6 V at minimum. Normal outbursts tend to reach around 13.5-13.7 V; superoutbursts can reach 13.0 V (as bright as 12.0 visually).
