Collegues,

    From Oct. 16.1 UT to Oct. 16.94 UT the XTE J1859+226 radio
counterpart went from a few mJy (for the last VLA observation)
to 110 and 70 mJy at 2.3 and 8.3 GHz as seen by the GBI. This
eclipses the puny 11 mJy peak event we have been following for
almost the last week and portends much more actively which is
somehow related to the jump from 0.7 Crab to about 1.4 Crab over
roughly the same period.

    I have a beggin request out for a VLA look tomorrow, but it
is the weekend and depends on an observer who may not even notice
my request.  However, this new event is strong enough for the
GBI data to tells us roughly what is going on in the radio.

Cheers, Bob
