AAVSO Special Notice #160

Request for observations of Z Cam
May 26, 2009

Further to AAVSO Alert Notice #390 (2008 November 13), Dr. Elmar
Koerding (CEA Saclay & Universite Paris Diderot) and collaborators
request optical photometry and enhanced monitoring of the UGZ dwarf nova
Z Cam.  An optical outburst of this source commenced around JD 2454977.0
(2009 May 25.5), and the star will be observed at radio wavelengths
using the Very Large Array in New Mexico.  Both visual magnitude
estimates and time-series photometry are encouraged.  CCD observers are
encouraged to perform V-band time series. If you have multiple filters
and can transform your data, multiple filters are encouraged, otherwise
single-filter observations are sufficient.  Since the source is
relatively bright (m(vis) ~ 11.0), please obtain good good
signal-to-noise in CCD observations.

For more information on this campaign please see AAVSO Alert Notice
Number 390: http://www.aavso.org/publications/alerts/alert390.shtml


Z Cam is located at the following (J2000) coordinates:

RA: 08 25 13.20 , Dec: +73 06 39.0
