Hello. 

Is there a spectroscopist who can study the spectral class of a mysterious star called GP Orionis?

Some of my sources say it is an M0, M2, SC7/8 or C8 star. 

I have not observed GP Ori yet. 

But I plan to in about a week's time.

This AAVSO website have plunged for C8 which is exceptionally rare type of carbon star. 

I would be delighted to hear from anyone here on AAVSO. 

Thank you from Aubrey. (Gath)

I'll give you all another 7 days to reply on the above post. 

Am I putting it in the wrong forum?

I just do not know. 

Aubrey.
