. NEVER look directly at the sun without a proper solar filter! . We have lots of different equipment available for use. Here you see our 6" solar filters. Our club always recommends that you use a FULL APERTURE solar filter. In the picture you will notice a TYPE 2 filter for VISUAL use and a TYPE 3 filter for PHOTOGRAPHIC use. Here is an easy way to remember which type solar filter you need for VISUAL OBSERVING: You have 2 EYES so you need a TYPE 2 filter!! .

MASTER OT J035815.59+214117.9 discovery - dwarf nova outburst MASTER-Kislovodsk auto-detection system discovered OT source at (RA, Dec) = 03h 58m 15.59s +21d 41m 17.9s on 2015-11-18.89742 UT. The OT unfiltered magnitude is 17.1m (limit 18.1m). The OT is seen in 3 images. There is no minor planet at this place. We have reference image without OT on 2010-12-03.85624 UT with unfiltered magnitude limit 20.2m. Spectral observations are required.

K. Baur ETH Zurich Zurich, Switzerland karin.baur@math.ethz.ch -filtered mo dules for a self-injective Nakayama algebra We describe the class of -filtered modules without self-extension for the Auslander algebra of a certain self-injective Nakayama algebra. The motivation for this is to model the P -orbits in the nilradical of a parabolic subalgebra p = LieP where P is a parabolic subgroup of an even special orthogonal group. This generalises work of Bruestle, Hille, Ringel and Roehrle (1999). ...
