PLAN
----
	We have passed perigee and are ascending. Will perform CAL-ER
	OBSID 60925, then begin science observations again at 23:05 UTC
        with OBSID 3784, to establish the position and x-ray signature
	of a short-duration GRB.

	Radiation summary - Solar soft proton flux is very low (<20).
	No significant solar radiation events recently.
