Flaring blazar PKS 0736+01 (e.g., ATel #6731, #6742) is in a "Galactic plane" (b=11.4 degrees) ASAS-SN field that our survey started observing in December 2014. Two images obtained using the 14-cm ASAS-SN quadruple "Brutus" telescope on UT 2015-01-20.40 reveal a strong (delta V~1.4 mag) V-band flare of that object, see this figure for recent ASAS-SN V-band photometry. In particular, the last four ASAS-SN epochs had the following V-band photometry:

 
 UT Date         V     
2015-01-15.52  16.25 
2015-01-16.52  16.30 
2015-01-18.40  16.45 
2015-01-20.40  15.19
