We present deep BVI CCD photometry of the stars in the dwarf galaxy DDO 210. The color-magnitude diagrams of DDO 210 show a well-defined red giant branch (RGB) and a blue plume. The tip of the RGB is found to be at I_TRGB=20.95+/-0.10 mag. From this, the distance to DDO 210 is estimated to be d=950+/-50 kpc. The corresponding distance of DDO 210 to

High quality CCD cameras and powerful PCs are enabling advanced amateur astronomers to make high quality photometric and astrometric observations of a wide variety of solar system objects and to reduce them almost in real time. This has had important consequences for the observation of minor solar system bodies. In particular, new comets down as

The Global Oscillations at Low Frequency (GOLF) and the Michelson Doppler Imager (MDI) instruments aboard the Solar and Heliospheric Observatory (SOHO) give an excellent opportunity to search for solar low frequency oscillation modes previously undetected from ground based experiments. Presented here is a comparison of the velocity power spectra

1998 was one of the most exciting years ever for meteor observers. No less than three showers (the Pons-Winneckids, the Giacobinids and the Leonids) gave significant outbursts. In recent years important outbursts have also been detected from the Perseids, leading indirectly to the recovery of the lost Comet Swift-Tuttle and from the November

We present a comparison between ionized gas and stellar kinematics for a sample of 5 early-to-intermediate disk galaxies. We measured the major axis V and velocity dispersion radial profiles for both gas and stars, and the h_3 and h_4 radial profiles of the stars. We also derived from the R-band surface photometry of each galaxy the light
