Dear John and friends:
                                       It looks like Scorpius is keeping us
very busy these days...
It seems we were overlooking a very interesting star. Is it the nearest
compact binary to us? (asuming it is such a system)
                                       Fortunately it is in the same field
of BM Sco, which is in my observing program, so I can say that every time I
observed BM Sco there was nothing brighter than 6.6 in M6 (but BM itself).
                                       Furthermore, now that a lot of people
are monitoring V449 Sco, any outburst has a better chance to be observed. Is
there any ephemeris or prediction based on that "3- year period"?

Best regards,
Sebastian Otero

PS:   As soon as I can I'll try to get the Jaschek reference on V449 Sco.
