Continue running load MAY2801B. Do ACIS-I observations of MACS
J1149.5+2223, obsid 1656, and MACS J1423.8+2404, obsid 1657, as part
of a study of clusters of galaxies to determine q0 and H0. Then
several very short observations prior to perigee: Obsid 2167, ACIS-I
observation of 2MASSJ145331+1353; and ACIS-S observations of the
recurrent nova CI AQL, obsid 2465 and of the radio jet in NGC 266,
obsid 1610.
