Subject: [vsnet 2046] DELTA SCORPII

Delta Scorpii brightening continues.
Now I can confirm it , since the star is now even brighter than sigma
Sagittarii and alpha Ophiuchi.
Its normal state was 2.32 but several weeks before seemed to rise to 2.2.
Tonight's estimates were:

20000716.9285     THETA SCO 1.86 (1) V (1) EPSILON SCORPII 2.29    =   2.07
                                                          =  THETA CENTAURI
2.06                      =   2.06
                                 THETA SCO 1.86 (2) V (1) GAMMA CENTAURI
2.16  =   2.06

20000717.1236     EPSILON SAGITTARII 1.84 (4) V (1) SIGMA SAGITTARII  2.09v?
=  2.04:
                                                          =  ALPHA OPHIUCHI
2.08v?                                      =  2.08:

So the star is shining at 2.1, considerably brighter than usual.
I hope that some folks out there can do some photometry on Delta Scorpii.
We're probably in front of a new GCAS star.

Best regards,
Sebastian Otero.
