Free format text (please update) The planetary nebula K 648 is a member of the globular cluster M15, and is one of only three PNe known in Galactic globular clusters. Pre-repair HST images reveal that the nebula is strongly elliptical in shape, and shows blobs on either side of the central star, similar to those seen around PNe in the field that contain close-binary nuclei. Moreover, our study of archival frames of M15 suggests that the central star of K 648 may be variable. We propose to obtain a series of WFPC2 images of K 648 in U, B, V, and I, in order to ascertain whether the central star is a close binary, and if so to determine its period and analyze its light curve. Close-binary central stars in PNe provide the most direct evidence for common-envelope (CE) evolution. Determination of the binary system parameters in a globular cluster, where we know the age, distance, and progenitor masses, would provide completely unique constraints on CE physics. The observations, if successful, would establish the existence of the first pre-cataclysmic binary in a globular cluster, and would shed light on the current problem that recent HST observations are revealing fewer cataclysmic variables in globular clusters than expected from dynamical capture processes. Questions ! Free format text (please update) Observing_Description: We will obtain a sequence of U,B,y,R,I observations of the central star of K648, the planetary nebula in the globular cluster M15, in order to determine whether it is a variable star due to being a close binary. In addition we will carry out narrow-band imaging of the nebula in H-alpha and [O III]. The time allocation is 11 orbits. In order to increase the scientific return we will place the core of M15 in one of the WF chips and monitor it for variable stars. This requires a specific spacecraft U3 roll angle near 30 degrees, and that all frames be taken at the same roll angle once it is chosen. In order to cover possible binary periods between about 2 hours and 10 days, the gaps between the HST orbits must increase geometrically. The optimal strategy is to observe during HST orbits 0, 1, 2, 4, 7, 12, 20, 31, 47, 70, and 100, counting from an arbitrary starting point. SAA passages must not be allowed to interrupt this sequence. WE BELIEVE THIS SCHEDULING, THOUGH DEMANDING, CAN BE DONE IN A WINDOW AROUND OCTOBER-NOVEMBER, or alternatively in August using a large off-nominal roll angle. (August may be preferable in avoiding the SAA interruptions of the orbit sequence.)

The optimal ORIENT to achieve this is 30D, with an acceptable range of 350D to 90D (but as close to 30D as possible). This is the first visit, which observes K648 during 3 consecutive orbits, numbers 0, 1, and 2.
