[Aavso-photometry] NSV01485 is an UGSU-type dwarf nova

[Denis Denisenko]

Congratulations to Patrick on detecting the outburst and to Tony on 
finding the superhumps!  The preliminary value of period, if confirmed, 
may help to resolve ambiguity in my detection of orbital variation in 
quiescence.  Now the value of 0.0717d (14 revolutions per day) appears 
to be more likely one than 0.0771d alias (1/13 day).

As Kato-san said 10 days ago, "Wow!"  The object becomes even more 
interesting than originally thought!  Two outbursts by 5 magnitudes in 
10 days is unexpected (at least, for me).

Arne, Aaron (and other people at AAVSO): how can I upload the data of my 
NSV 1485 observations to AAVSO database?  What HD number should be used 
for this star?  I have hundreds of estimates covering the nights of Aug. 
26 - Sep. 10, but they are all in Sloan g (g') filter.  Should I mark 
them as V or what?  There are also observations back from this January 
at Caucasus with 15-cm telescope and from Ka-Dar observatory by Stas 
Korotkiy and their team with 0.35-m.  It would be very convenient to 
have all data on this star combined in one place!

And also, please check the info on this star in VSX.  As I wrote in 
[cvnet-outburst 8057] (see 
<http://ooruri.kusastro.kyoto-u.ac.jp/pipermail/vsnet-outburst/2007-September/001576.html>), 
the star ID in Simbad is incorrect!
