We present reliable, serendipitous x-ray detections found in three different deep ACIS imaging fields in two different energy bandpasses. We ran the Chandra X-ray Center's exttt{cell detect} source detection program on a ``soft band'' image (from 0.5 - 2.0 keV) and a ``hard band'' image (from 2.0 - 7.0 keV). The 3 high latitude fields investigated

The signature of the Solar-Cycle appears clearly in the p-mode parameters (Jiménez-Reyes et al. 1998, Libbrecht & Woodard 1990, and Anguera et al. 1992). At present, the study of the p-mode parameter variation is a very active topic in helioseismology where, thanks to projects like BISON, IRIS, GONG, LOWL and MDI, we are able for the first time to

We present results of analyses of observations of the X-ray source 2A 1704+241 with the ROSAT Position Sensitive Proportional Counter (PSPC) and the High Resolution Imager (HRI). 2A 1704+241 was first associated with the M-giant star HD 154791 based upon observations with the HEAO 1 SMC and the {Einstein} IPC and analysis of a spectrum of HD 154791

Several facts regarding the structure of NGC 604 are examined here. The three main cavities produced by the mechanical energy from massive stars, which in NGC 604 are spread over a volume of 106 pc3, are shown here to be undergoing blowout into the halo of M33. High-resolution long-slit spectroscopy is used to track the impact from massive stars

The possible existence of the June Lyrid meteor shower is examined from data in the IMO archive from 1984 to 1997. It is concluded that the activity is weak but detectable in most years. The mean activity curve shos a symmetrical rise and fall about a maximum of ZHR = 3, although annual variations are undoubtedly present. The solar longitude of the

We present the first part of the first large and homogeneous CCD color-magnitude diagram (CMD) data base, comprising 52 nearby Galactic globular clusters (GGC) imaged in the V and I bands using only two telescopes (one for each hemisphere). The observed clusters represent 75% of the known Galactic globulars with (m-M)V
