2013 Annual Activity Report for the Variable Star Section
There can be no doubt that 2013 has been one of the most exciting years for the section for a long time.
The turbulent star R Scuti went through a great period of activity throughout 2013 and we saw the star jumping back and forth from between naked eye visibility and back again to being visible only in telescopes and binoculars. R Scuti varies between magnitudes 4.2 to 8.6 and this year we saw the star go through its entire magnitude range. The light curve below shows the stars activity throughout 2013 and is constructed using observations from SPA members and others from around the world.
Back in April/May of the year we were treated to lovely brightening of the star Chi Cygni. This star has an incredible magnitude range from 3.3 to 14.2 and during the first part of the year we saw the star hitting magnitudes as high as 3.5 making it easily visible to the naked eye. Sadly the brightness was not to continue and the star steadily faded throughout the coming months and at the time of writing this review (Feb 2014) Chi Cygni’s current magnitude estimates are a faintly 12.6 !
