Hi CBAers,

This looks like it might be a rewarding target.  It's a new one on me. 
Send any report to cba-chat so we can find out whether it's worth pursuing.

Lanning 420, classified as variable type n:, has brightened from ~ 19
mag to 16 and is now showing signs of superhumps.
Lanning 420 was last observed in outburst on July 26, 2007 where it was
rabidly declining at a rate of .3 mag/hour with no visible superhumps.

I would be interested in receiving any time series data during this
outburst period.

The object is well placed in Cepheus for Northern observers at:
22 01 04.04 +58 48 48.4

Clear skies,

Steve Brady
