Special Notice #347: Correction to AAVSO Special Notice #346
April 9, 2013: In AAVSO Special Notice #346 (http://www.aavso.org/aavso-special-notice-346), IU Leo was said to have a close companion about 2 arcsec to the NE. This is not correct - it is IY UMa that has this close companion.
We extend sincere apologies to Dr. Szkody for misquoting her and to our readers for the error.
This AAVSO Special Notice was compiled by Elizabeth O. Waagen.

Alert Notice 481: Nova Survey participation requested
March 19, 2013: The AAVSO solicits participation in an online survey from our member and observer communities. The survey is being conducted in advance of an upcoming long-term observing campaign that will be launched in mid-April 2013. We are seeking participation in this survey from as broad a sample of the AAVSO community as possible, and your responses will help us gauge the effectiveness of the campaign and serve the observer community better.
Alert Notice 473: T Tauri stars observing campaign
November 6, 2012: Darryl Sergison (University of Exeter) has requested AAVSO assistance with a campaign he is organizing on six T Tauri stars. He writes: "In Autumn 2013 I [and my PhD supervisor Tim Naylor of Exeter University are] undertaking a new study into the nature of pre-main-sequence low mass stars, using time series optical spectroscopy and UV-Visual-IR photometry...to build a clearer picture of the environment around young solar-type stars and characterise their various disc, accretion, and outflow structures.
