... In this paper we present the results of detailed B, V, R, I, and H study of the isolated nearby blue compact dwarf (BCD) galaxy NGC6789. Judging from the literature the observed galaxy has not been resolved into stars up to now. ... The distance of the galaxy, estimated from the tip of the red giant branch (TRGB) is 2.1 Mpc which places NGC6789 close to the Local Group. ... Key words: nearby galaxies: dwarf galaxies (NGC 6789): distance moduli: star content . ... Distance. ...

... This study reveals for the first time the existence of bi-directional jets, which are a signature of magnetic reconnection, occurring along coronal hole (CH) boundaries. ... K) emission lines in an equatorial extension of a polar coronal hole, known as the ``Elephant's Trunk'' coronal hole, show small regions of a few arc-seconds size with strong blue- and red-shifted emission reaching Doppler shifts of up to 150km s, i.e. bi-directional jets. ...

... Up: Data Analysis and Processing Techniques . ... Also, a method for quality control of CCD observations is suggested. ... Everyone who observes a celestial object using a CCD detects moving celestial objects as a ``by product''. ... We hope that our investigations may be useful for near-Earth space control and also for searches of the moving celestial objects through analysis of old and new CCD frames obtained at any amateur or professional astronomical observatory. ...

The ephemeris data for spacecraft and target bodies are normally combined in a single file called the SPICE SPK file. ... Attitude data is contained in the SPICE CK file. ... Several miscellaneous kernel files - spacecraft clock (SPICE SCLK file) and leapseconds (SPICE LSK file) - are also part of SPICE; these are used in converting time tags between various time measurement systems. ...

Next: The Orion OB1 Up: Contents Previous: This work . In this chapter, I will define the sample of stars which will be discussed throughout the remainder of the dissertation. I define two coeval sets of PMS stars located in the Orion OB1 association. ... I then describe the X--ray observations which were used to find the PMS stars in this association. After this, I spend several sections detailing the photometric observations and difficulties in placing objects on the H--R diagram. ...

... Views of Martian Clouds . ... Although not as pronounced as on Earth , clouds are common features on Mars. The Martian atmosphere has only a trace of water vapor; however, the temperature and pressure is such that the atmosphere is usually close to saturation and produces clouds.

... The very demanding goal of 50 milliarcseconds root-mean-square (mas RMS) for the astrometric precision of the Sloan Digital Sky Survey implies that focus and collimation motions of the secondary must be very smooth.
