[vsnet-campaign-blazar 8] Re: PKS2005-489 brighteningcontinues
Hi observers and interested parties,
a similar brightening was observed three (or four?) years ago when I started monitoring this blazar. I did not have any decent comparison stars then but with hindsight I think it might have been a bit brighter than it is at present.
Two weeks ago I posted a comparison sequence, which I like to update now in view of the actual Tycho 2 value of the brighter star. The magnitude of this comparison star has become important since the brightening.
USNO-A2.0 / RA - DE / V
0375-38542386 / 20 09 48.7 -48 48 51 / 117 (was 119)
0375-38530007 / 20 09 02.3 -48 45 34 / 127
0375-38539714 / 20 09 38.7 -48 46 18 / 135
Best regards,
Berto
