ASAS 190512+0514.2
Grzegorz Pojmanski, Warsaw University Astronomical Observatory has 
reported on VSNET-ALERT 8440 that a variable object has been found with 
the ASAS3V instrument of The All Sky Automated Survey (telephoto lens 
180/2.8, diameter 65mm + CCD + Johnsons V  filter) and located at:
RA 19h 05m 12s  DEC +05 14'.2 (2000)

V magnitudes: June 3 (07.37UT), <14; 9 (05.45), 11.0; 10 (05.25), 10.5. 
The last result was obtained through clouds.
Light curve and images can be found on

We have subsequently received an e-mail from Arto Oksanen (Finland) 
confirming this outburst, the star is about V=10.84. Using a remote
operable Rent-A-Scope (New Mexico, USA) 30 cm Mewlon telescope and FLI 
Dream Machine CCD, I took B, V and Rc filtered images of the target. My 
V-filtered image taken on June 10 (08:38UT) and differential photometry 
using GSC 470:857 (ASAS V-band mag:
10.99, Equatorial 2000: 19h 05m 41s +05 12'35") as reference:
