Evolution of the light curve of V410 Tau during 1986-1997
Homogeneous UBVR observations of the spotted T Tauri star V410 Tauduring 1986-1997 are presented. Over the twelve years, this star hasexhibited periodic light variations (P = 1.872095 days), which areattributable to the presence of cool spotted regions on its surface. Thestability of the phase of minimum light throughout the entire period ofobservations was confirmed. Model calculations show that, first, thespot temperature is lower than the photospheric temperature at least by1450 K, and, second, spotted regions cover from 29 to 42% of the visiblestellar hemisphere at maximum light and from 61 to 67% at minimum light.The causes of the year-to-year changes in the mean level and amplitudeof the light curve are discussed.

| The Henry Draper Extension Charts: A catalogue of accurate positions, proper motions, magnitudes and spectral types of 86933 stars
The Henry Draper Extension Charts (HDEC), published in the form offinding charts, provide spectral classification for some 87000 starsmostly between 10th and 11th magnitude. This data, being highlyvaluable, as yet was practically unusable for modern computer-basedastronomy. An earlier pilot project (Roeser et al. 1991) demonstrated apossibility to convert this into a star catalogue, using measurements ofcartesian coordinates of stars on the charts and positions of theAstrographic Catalogue (AC) for subsequent identification. We presenthere a final HDEC catalogue comprising accurate positions, propermotions, magnitudes and spectral classes for 86933 stars of the HenryDraper Extension Charts.
