TYC 688-46-1 Carbon Star observed was created by flt158

Hello everyone. 

It's quite a number of years since I observed a carbon star in Orion with my William Optics 158mm f/7 apochromatic refractor. 
In 2011 I had seen 4: W, RT, BL and GK Orionis. 

As the Hunter is now visible in my southern sky, it was high time to find a 5th. 
I found this one on 1 March 2022 
TYC 688-46-1 is near the open star cluster NGC 1662. 

Its Right Ascension is 4 hours 51 minutes and 24.66 seconds. 
The Declination is 10 degrees 45 minutes and 17.8 seconds. 
Its magnitude is 11.2. So it is very faint. 

Its spectral class is C or R with a Johnson B-V of 1.387. 
It has 2 alternative designations: DO 877 which I found on Simbad and GSC 688 46 on Guide 9.1. 
Simbad also shows another orange star 28 arc seconds from TYC 688-46-1. 
But the only designation I have for this second orange star can be found on Guide 9.1: 3UC202-019328. Its magnitude is an even fainter 11.5. 

Still I could just about see these 2 dim orange stars at 112x.
The view was so much better at 167x, 225x and 280x, 
I know there is no double star designation for these 2 stars. 
But I found great delight in observing them as they are in close proximity to one another. 

At 280x, I could see that TYC 688-46-1 has a stronger orange colour. 

And it is my 111th observed carbon star overall. 

Thank you for reading my report. 

Comments and images are very welcome. 

Clear skies from Aubrey.

Hi Aubrey, 

We were both out observing in the same night, but from different locations :) 

Some wonderful details in this report, and it was great to read you observed more carbon stars - congrats! 

Clear skies,
