Ohlert, Astronomie Stiftung Trebur Germany Holger Lehmann, Thueringer Landessternwarte Tautenburg (TLS) Germany To create a new Doppler image of the spot distribution of V410 Tauri 13 spectra were taken at different rotational phases of the approximately 1.872 days period of the weak-line T Tauri star. The data were acquired on 13 nights spanning 128 days in late 2004 and early 2005 using the Coude Echelle Spectrograph of the Thueringer Landessternwarte Tautenburg 2m telescope and a 2000 x 2000 CCD detector. A wavelength coverage of 4750 - 7070 A was obtained. Furthermore photometry has been measured simultaneously with MONICA at the 80 cm telescope at Wendelstein Observatory. A Doppler image was derived using a Maximum Entropy method and several photospheric absorption lines, like e.g. the Ca I line at 6439.1 A. All images calculated show a spot distribution dominated by a high-latitude spot. This spot seems to be long-lived because it already appears in Doppler images from data taken in 1990 by Joncour et al., in 1992 by Strassmeier et al. and in 1993/1994 by Hatzes. The photometry is used to compare it to an artificial light curve derived from the calculated Doppler image to check the quality of the resulting image, while the Doppler image itself is of course compared to previous images. Moreover the photometry is taken to investigate if there still is a tentative cycle in the mean V band magnitude with a length of 5.4 yr which was found by Stelzer et al. in 2003 and supposed to be the first tentative detection of an activity cycle on a PMS star. ----------------------------------
