[vsnet-alert 23854] Recent V1047 Cen observations

Mon Jan 13 22:54:50 JST 2020

Nova Cen 2005 has further brightened (and reddened) since last season:

JD / CCD-V / CCD-Ic / CCD-Rc

2458728.25 14.84 12.90 13.75
2458859.62 14.20 11.65 12.66
2458860.55 13.86 11.40 12.45
2458861.57 13.96 11.73 12.68

The table shows fast variations in all bands of a red(dened) object.
Timeseries unfiltered photometry over 0.2d (around 2458861.5) confirm this
fast gradual variation. No clear short period is shown but there's a hint
at a longer period.
The 8.66h period from the TESS light curve (ATel 12889) could be confirmed
and improved with TS observations of long duration, possibly in March 2020.

Observations above were made at CBA KKO.
