A marked change has occured with this nova in the last 24 hours, not only is
it currently declining at 1.4 mag/day, it is becoming increasingly reddened
in V-I at a rate of 0.9 mag/day.
By happenstance, the V-I colour at around 20:36 UT was +0.83, which was the
same as that measured earlier today at about 00:01 UT. It has therefore
switched from a blueing trend to a strong reddening trend today.
