Data Release 10 is now available.

Through a grant from the Robert Martin Ayers Sciences Fund, the AAVSO is performing an all-sky photometric survey. This survey is conducted in eight filters: Johnson B and V, plus Sloan u', g′, r′, i′, z_s and Z. It is valid from about 7th magnitude to about 17th magnitude.

March 27, 2012:  A possible nova in the LMC [Nova LMC 2012] discovered at unfiltered magnitude 10.7 on 2012 March 26.397 UT (name of discoverer not given) was reported on the IAU CBAT Transient Objects Confirmation Page (TOCP). Spectra indicate the object may be a recurrent nova.

J. Hambsch reports that as of March 28.04 UT, the object appears to be fading fast and is at least one magnitude fainter than 24 hours ago.
