===

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,
