Dear All,

In a moment, Dan Reichart will circulate empirical estimates of
the expected brightness of GRB990123 tonight in a number of filters.
The afterglow is expected to be so bright that multiwavelength
observations are probably a priority -- extending into the v-, b-,
and perhaps even the u-bands.

NIR observations would also be very important in determining the
spectral and temporal behavior of this burst.  Such observations
might be attempted just before dawn, when optical observations
would not be as effective.

Lastly, the optical afterglow is so bright that we might want to
consider whether taking the observations in such a way that
detection of or limits on any optical variability could be derived.

Good observing!

                                  With warm best wishes, Don
