Special Notice #96: VSX J074727.6+065050 rebrightening [DY CMi]

February 7, 2008: Further to AAVSO Special Notice #92, the recent optical transient in CMi, VSX J074727.6+065050 [DY CMi], appears to have rebrightened after fading to below V=16.0. Eddy Muyllaert (Oostende, Belgium) reports via the AAVSO, BAAVSS, and VSNET alert newsgroups that this star has rebrightened to m(vis)=13.3 on 2008 Feb 06.8542 UT (JD 2454503.3542). The most recent observations reported to the AAVSO (2008 Jan 31.1378; JD 2454496.6378) place the star at V ~ 16.8. This indicates a significant rebrightening has since occurred. Similar rebrightenings are typical of WZ Sge-type objects, providing further evidence for a WZ-type classification of this OT. Further observations of this star are encouraged. We note that a V and Ic sequence is available via VSP, but that the reported U and B band comparison star magnitudes are incorrect; magnitudes for these bands will be corrected shortly.

VSX J074727.6+065050 is located at RA: 07 47 27.64 , Dec +06 50 50.0   (J2000).
