[Berto Monard astroberto13m@gmail.com via vsnet-alert]

This is a non catalogued 'new' blue object with an outburst amplitude >
7mag

Observations were done last night at CBA KKO:
Unfiltered observations show no clear modulation at mag 13.93CR.
Filtered photometry on UT Jan 28.90 : 14.2V, 13.95R, 13.92Ic
Astrometry vs UCAC4 on unfiltered images give a (2000) position: 06 07
30.72 -01 01 47.1  with estimated uncertainties 0.04 and 1.5 respectively.

Well done to the Brasilian discovery team!
