Light curves from observing season 2013-2014

Here are some of the best lightcurves that I was able to obtain during last observing season, 2013-2014. I was observing mostly some brighter Mira stars but also representatives of few other variable types. All observations have been made visually either with 4” refractor or 10” Newton -type reflector. Observations have been mostly made in Turku, Finland, but also in some other locations.

R Cas

R Cas is a Mira -star in Cassiopeia. During last season I observed the brightness of the star to reach it’s maximum, little bit less than 6 magnitudes, and then decline back to minimum, about 11 magnitudes.

T Cas 2013-2014
T Cas

T Cas is another Mira -star in Cassiopeia. It has a characteristic double-humped maximum, but I wasn’t able to observe it during this season. Instead, I observed the star getting fainter during Autumn and the reaching it’s minimum in spring 2014.

T Cep
T Cep

T Cep is a Mira -star in Cepheus. It was very fun and rewarding to follow the ascent of it’s brightness, which peaked in 6 magnitudes in late April 2014.

Omi Cet
Omi Cet

Omi Cet, a.k.a Mira, is the prototype of it’s class, the Mira stars. Omi Cet is a bright naked eye -object at it’s maximum, but it have to be observed by means of  a telescope in it’s minimum. I observed this star during the course of it’s descent towards minimum. It reached it’s minimum light around Christmas 2013.

R Cyg
R Cyg

R Cyg is a Mira -star in constellation of Cygnus. I observed this star around it’s maximum from late July to early November 2013. The maximum waa around August-September 2013. This time the maximum was little bir less than 6 magnitudes.

SS Cyg
SS Cyg

SS Cyg is a dwarf nova -type cataclysmic variable, and it is among the brightest of it’s class. When in outburst, the star reaches magnitude 8, and then descents back to minimum light, about 12 magnitudes. During the season 2013-2014, I was able to catch this star in outburst twice.

V339 Del
V339 Del

V339 Del aka Nova Del 2013 was the first nova that I have ever observed in my life! And what a spectacukar nova it was! It was among the 20 brightnest novas ever observed! The nova appeared in the sky around mid August 2013. It reached it’s peak brightness around 16th of August, then it was as bright as 4,8 magnitudes, and it was also visible with naked eye in a dark place! During the course of Autumn 2013, the star was gradually getting fainter, and it also platooed during September 2013. During the platoo-phase, it’s brightness was descending only very slightly. This object was one of the highlights of the season!

R Leo
R Leo

R Leo is a bright Mira -star in Leo. During the season 2013-2014 I observed this star to ascent from it’s minimum to maximum, and then back to minimum. It peaked around December 2013, then it was as bright as 5 magnitudes.

R Tri
R Tri

R Tri is a Mira -star in Triangulum. I was able to witness a maximum of this star, about 6 magnitudes in December 2013.

Z Uma
Z Uma

Z Uma is a semiregular variable in Ursa Major. It has a pleasently large amplitude for it’s type, which makes it easy to observe. I observed the star to reach it’s maximum in January 2014 and the descent back to minimum.

    Nice observations! Do you have a lightcurve of Algol? I haven’t observed that particular star too much, but it’s an interesting system, nonetheless.
