C/1995 O1 (Hale-Bopp) was observed in daylight on 16 days between 1997 April 1 and 1997 April 28, five of which had long time sequences (up to 10 hr of data), using the near infrared CAIN camera on the 1.5 m Carlos Sanchez Telescope at Teide Observatory (Tenerife, Canary Islands, Spain). Three spiral dust jet structures were observed for several

We present Hα, [NII]6583 and 6-cm continuum images of the emission line nebula K3-35. The optical images reveal an extended nebula (size ~=11x9arcsec^2 in [NII]) in which most of the emission originates in a very narrow (width 0.7-1.3 arcsec) S-shaped region which extends almost all along the nebula (~=7 arcsec). The 6-cm continuum emission also

SABIO is currently at the beginning of the specification phase at the Instituto de Astrofisica de Canarias (IAC). This system is aimed at providing full control over the complete set of telescope operations, ranging from tools for proposals submission and data entry until the final scheduling during the observations. SABIO will also manage the link

A narrow-band Hα image and high-resolution spectroscopy have been obtained in order to investigate the nature of S266 and its central star MWC 137. The analysis of the stellar and nebular spectra suggests that MWC 137 is a B[e] supergiant located >= 6 kpc away from the Sun and not a Herbig Ae/Be star, as it has been traditionally classified

A comparison between the results of applying a ring diagram analysis to two data sets is described in order to check the quality of the two sets and the reliability of the method. The series used have been obtained with two different helioseismological instruments with the same spatial resolution. A section of 30 × 30 deg2 about the disk center has
