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.
