Hello all,
        FYI, here's what I know about GRB 990123 observation plans tonight:
At Kitt Peak, where there is moderate intermittant cirrus, I plan to
trigger Target of Opportunity observations at the 4m to get a U band
flux; van Paradijs et al will try for BVRI target of opportunity observations  
with WIYN; and Koekemoer will try for a brief K band image at the 2.1m.
The time available at the 4m and 2.1m is limited (15 to 60 minutes
integration or so), while WIYN should be on source as long as
astronomically possible.
        The main thing we can't do tonight is spectroscopy (no appropriate
instrument mounted).  Chryssa Kouveliotou tells me that Palomar may try
for a spectrum, but their weather is worse than ours.  Flagstaff is clouded
out on my latest weather map; Fred Vrba says they (USNO) won't be able to
do NIR tonight but may try optical observations if clear.
        So, my unsolicited opinion is that a spectrum should be APO's
first priority tonight if DIS can reach R=21 or so, and that NIR
imaging would be a sensible second priority, since there is better
redundancy in optical imaging than in either spectroscopy or NIR
imaging.  Only if everyone else is clouded out might I rate optical
imaging above the other options.
	Best regards,                                   James Rhoads.
