SUPERNOVA 2011B IN NGC 2655
Further to the comment on TA E-=Circular 2709 regarding uncertainties in 
comparison star magnitudes from catalogues, the AAVSO has now carried 
out photometry and made available a new chart. To download visit:
http://aavso.org/
and type in SN 2011B (inclusion of space important) and click 'create a 
finder chart'. There are options after the initial result to set scale 
and orientation to suit your telescope/CCD equipment.

Guy Hurst reports revision (cf E2709) and extension to results using the 
Sierra Stars 0.61-m Cass with a V filter:
2011 Jan 26.60UT, 12.9; Feb 1.34, 13.1; Feb 6.328, 13.5

Please send results daily to the editor quoting:
Date and Time (UT, h m), magnitude, full estimate, filter, instrument 
and sequence reference.
If you have sent earlier results which need re-reduction on this latest 
AAVSO sequence please advise amendments.
