[vsnet-alert 2321] Re: BL2005-489

Hi,

for those interested in monitoring this blazar, I like to share the
sequences I use. They were calibrated against nearby GSPC fields using
USNO-A1.0 as the transfer medium and verified using USNO-A2.0.
In the table are USNO-A1.0 codes for the comparison stars, (2000)
coordinates in RA and DE (in HHMMSS and DDMMSS respectively) and
positions in arcminutes relative to PKS 2005-489.

Code Name  : RA  /  DE (2000) : Pos. relative to PKS : Magn (Berto)

0375-38752207 : 200949-484852 : 4.0' E, 1.0' N : 11.9  
0375-38749537 : 200939-484618 : 2.4' E, 3.5' N : 13.5
0375-38745438 : 200923-484459 : 0.4' W, 5.0' N : 12.7

These sequences were sufficient to monitor PKS 2005-489 through its
stages. Hopefully there isn't a variable amongst them...

X-ray outburst in BL2005-489

The RXTE All Sky Monitor has detected increased X-ray flux 
from the BL Lac object 2005-489 (J2000, degrees: 302.3558 -48.8316).
During the interval 1998 Oct 11-28, the flux has been in the range of
4 to 10 mCrab at 2-12 keV, which is a factor of 2 to 3 above the 
its typical intensity during 1996-1998.  Observations at other 
wavelengths are strongly encouraged.
