urgent request for spectroscopic observation
With a friend we are conducting a photometric survey in the Milky Way. This week we discovered what looks like an unknown eruptive or cataclysmic star in outburst. Its position:
18 40 29.13 -27 09 59.3 (J2000.0)
A field image can be seen here: http://www.aspylib.com/alerts/2013-09-23/follow-up_25Sep2013/imageRTarot_25Sep2013.PNG
Measurements in BVRI filters show it is clearly blue. We measure its V magnitude around 13.4 whereas all catalogs indicate much weaker V values (V=15.9 derived from UCAC-3, V=16.4 in YB6 and V=17.3 derived from CMC14).
We are monitoring the star photometry with telescopes in different locations to cope with bad weather. So far, so good..
Unfortunately, we are not equipped to measure its spectrum! We fear we will not manage to find out the variability type without one. So we're desperately looking for some help..
Thanks a lot
