Hello, all carbon star admirers.
On Sunday 7th March 2021 I set up my William Optics 158 mm F/7 apochromatic refractor in my back garden.
The Sun had set at 18.14 UT.
The air temperature was 2 degrees Celsius.
But there was no wind at all.
Within 5 minutes after sunset I found Aldebaran. It makes me wonder if I could spot Alpha Tauri in my William Optics 70 mm F/6 apochromatic refractor well before sunset.
Anyway, I had the desire to seek out my 6th observed carbon star in Taurus which has the designation C* 3239.
I discovered on Simbad another alternative designation which is TYC 659-631-1.
My Guide 9.1 DVD gives the same star one other designation: GSC 659 631.
The Right Ascension is: 03 hours 59 minutes 36.81".
The Declination is: +08 degrees 29 minutes 0.71".
There is no problem with the spectral class.
It's either C or R.
This carbon star is seriously faint.
The magnitude is +11.6.
I did somehow manage to spot it at a fairly low 112X. (There was no Moon visible.)
At that power the star was roughly halfway between TYC 659 1275 (mag = 9.8) and TYC 659 1081 (mag = 10.4).
However I started to notice its tangy orange colour at 167X and 225X.
But at that point C* 3239 was completely alone in the field of view.
In closing I am delighted to say that this carbon star is the 98th I have observed.
