We report on Chandra ACIS-S observations of five type I X-ray bursters with low persistent emission: SAX J1324.5-6313, SAX J1752.3-3128, SAX J1752.3-3128I, SAX J1324.5-6313V, and SAX J1818.7+1424. We designate candidate persistent sources for four X-ray bursters. All candidates are detected at a persistent luminosity level of 1032-33 erg s-1

We have detected two globular clusters in the nuclear region of M31 with both Chandra and HST. These detections allow us to register the Chandra and HST images and therefore determine relative positions to ~0.1''. This improved positional accuracy shows that (contrary to our earlier reports) neither CXOU J004244.2+411608 nor CXOU J004244.2+411609

As part of our ongoing Chandra/HST M31 transient program we report on a Chandra ACIS observation of M31 containing the new transient source reported by Pietsch et al. (2008, ATel #1674). A single 5ks observation was performed on 2008-09-01.32 UT. The Chandra coordinates for this source (subject to the boresight correction) are RA(J2000) 00:43:20

We will report the results from an occultation of P126A by Pluto on the night of 2002 July 20 UT. The event was successfully observed with a 0.4-m telescope at Mamiña, Chile under photometric conditions. Additional data were collected at CTIO on a 0.6-m telescope with heavy interference from clouds. The CTIO observations preclude an occultation at

This paper presents high-resolution (0.6") spectropolarimetric observations of very quiet solar regions. We make determinations of the magnetic flux density, intrinsic field strength, and magnetic filling factor in these regions. Our results confirm other previous works in that most of the internetwork flux is in the form of intrinsically strong

With the recovery of comet 103P/Hartley 2, the target of the EPOXI mission, we have begun the characterization of the nucleus necessary for the mission. Observations from past apparitions of this comet show that it typically begins activity while far from the sun, near r = 4 AU (about 450 days pre-perihelion). This makes obtaining information about
