R Leonis on the rise

6 posts in this topic

Is anyone paying attention to R Leonis these days? Data in the AAVSO site indicates it is about mag 9 and around midway through the raising phase. With a raising time of about 4 1/2 months, I recon that we may have a chance of observing the maximum in about two months, or mid May.

In my case (at latitude 59.4) that would be more or less at our "light limit" after which we will not have any real darkness until August, so I understand that I will possibly miss the maximum. Nevertheless, the prospect of getting some better weather during the spring and observing the star increasing its magnitude is in itself a gladdening thought. That would definitely bring some joy to me since we had a dismal cloudy winter here.

Look at the charts below, R Leonis is very easy to find and will surely be fun to follow.

Cheers!

Thanks for the reminder, but rain then trees got in the way this evening,

However R CrB is still presenting nice in binos at 2am local, and so was a consolation :)

Got it `Stellarium` thanks

 

Yes, it is Stellarium. The upper chart is made using Light Curve Generator, an online tool in AAVSO site.

      Just a friendly reminder to have a watch at the recurrent nova T CrB, now that we are approaching its season. As discussed last year, T CrB may possibly be approaching the time of its next outburst. See this fine article in Sky & Telescope. T CrB has been increasing its brightness somewhat since 2015, in a manner that is reminiscent from its behavior in 1938, just 8 years before the 1946 outburst. Do not miss the chance to assist to this great show! Get an eye on this star. It is easy to find and, who knows, she may give us a lovely surprise "soon".
      I just wrote a commentary on this in my astro blog, if you are interested you may have a look here.
      Cheers!

      Just to tell everyone interested that the cataclismic variable SS Cyg is in outburst right now and since about a day or so and still raising!
      Cheers and enjoy!

      Just to chime that the long period (Mira type) variable star Chi Cygni is now above mag 9 and therefore well within the reach of a variety of binoculars. I spotted it a couple of nights ago with my 15x70, at estimated ~8.7 +/- 0.2 mag. May be some of you might want to watch it creep slowly upwards in the coming months, hopefully reaching naked-eye visibility before it sets for the season. Cheers and clear skies!

      SS Cyg is since a few days ago in its recurrent outburst phase at about 8.3 mag. This is its fourth outburst in 2016. Those of you who enjoy some darkness at night these days around the solstice may want to watch the show of SS Cyg falling back precipitously to its lower magnitude state. For my part, as there is nothing resembling darkness here, I will content myself looking at the observations of others while I wait for the next outburst in August
