[vsnet-alert 14330] Re: OT_J094854.0+014911 = CSS120315:094854+014911

Dear colleagues,

We found OT_J094854.0+014911 = CSS120315:094854+014911 was already
bright at 14-15 mag on Mar. 11 in the course of the MISAO Project,
from survey images by Nobuo Ohkura with 350-mm camera lens + f/4.0
reducer lens + SBIG STL-1001E.

Unfortunately, the object is slightly under the detection
limit... Please see the image:
