HV Vir fading and reddening

 HV Vir started fading with a reddening trend. 
We observed HV Vir with TRISPEC/KANATA. 
Our preliminary analysis can be seen at:

Combining with the data on 14 Feb, we performed 
a preliminary period analysis. 
The early superhump period was estimated to be 
0.0569 +/- 0.0004 d, which is significantly shorter 
than the ordinary superhump period, and in agreement 
with the early superhump period reported in previous 
outbursts of HV Vir.
