Welcome to my
Variable Star Pages
22″ Telescope “Infinity”
The science of Astronomy is unique. A great deal of astronomical research depends on the work of highly skilled amateur astronomers that provide a pivotal role in the constant monitoring of variable stars.
I observe and monitor variable stars particularly the cataclysmic (explosive ) variable stars (CVs) for outbursts. Recorded observations are then sent to various variable star organizations which include, the American Association of Variable Star Observers (AAVSO), the research section of the Royal Astronomical Society of New Zealand, Variable Stars South (VSS) and the Variable Star Network (VSNET) a global professional-amateur network of researches in variable stars.
These pages tell my story, show a selection of light curves, links to articles, dramatic events, transient objects and cataclysmic variables (CVs).
The current observations page will show my latest observations, outbursts detections and activity on variable stars.

CURRENT OBSERVATIONS
Latest outbursts detected
April 7, 2018
CENV342 180407.426 159 outburst
HYAV392 180407.429 145 outburst
NORHP 180407.460 132 outburst
ORICN 180407.417 128 outburst
TUCVW 180407.440 152 outburst
The Hubble Space Telescope will be observing the dwarf nova GW Librae on Aug.31 / Sept.1 2017. The Space Telescope Science Institute (STScI) needs constant updates on the current state of GW Lib to make sure it is at minimum. My latest observation sent at magnitude 16.5 shows it is around minimum.
GW Lib was discovered in 1983 as a 9th magnitude object. On April 12, 2007 I noticed GW Lib was rising to outburst, the first recorded outburst in 24 years since the discovery! GW Lib has had no further outbursts. My visual light curve of the 2007 outburst which lasted over 70 days. More here.
Observation of a Deep Visual “Eclipse” in the WC9-Type Wolf-Rayet Star, WR 76
My paper was published with Peredur Williams, Institute for Astronomy, Royal Observatory, Edinburgh on ” Observation of a Deep Visual “Eclipse” in the WC9-Type Wolf-Rayet Star, WR 76 ” One of the deepest found so far in these types of stars. A real challenge visually as the eclipse is well below 17.0 magnitude.
UY Puppis – A New Anomalous Z Cam Type Dwarf Nova
My paper was published October 2016 with Mike Simonsen on UY Puppis – A New Anomalous Z Cam Type Dwarf Nova. UY Pup is now one of only four known anomalous Z Cam stars!
Wolf-Rayet Star, WR 53
My paper published on the discovery of the first ever recorded eclipse in the Wolf-Rayet star WR 53. After 5 years of constant monitoring we now have a new variable star!
Wolf-Rayet Star WR 53 – Added to the International Variable Star Index July 2015.

G’day Rod!
I have now decided to add WW Cet to my programme. I like the ‘southern challenge’ and currently do a few stars in Puppis and southern CMa.

Hi Michael,
WW Cet used to have outbursts up to 10.9 but have not seen it this bright for many years now. There are plenty of variables in the Southern sky’s to look at but not many active observers so keep up with the challenge!

Congratulations on your 200,000 visual observation milestone.
Absolutely fantastic!

Hi Rod,
Very nice website. I’ve just added a link to it from my own.
WW Cet is interesting. -11d too low for me though. Bang in the middle of the ‘orange glow’ from Birmingham city centre. Too bad.
Clear skies,
Gary

Thanks Gary. I haven’t added a links page on my site yet, but when I do your site will be on there.
Yes, it will be interesting to see how WW Cet behaves for the rest of the 2010 season!
Cheers,
Rod.
