Re: Another New One?

Tom-

I am hoping I can find someone to help me write a paper if I can verify this
and if it is indeed "new.

Michael-

I am going to take unfiltered and perhaps "V" photometry. I don't have the
full BVRI set, though. If anyone would like to help me with the followup
photometry we can put all our names on the paper!

Cheers,
Michael
