B2 1633+38 (4C +38.41) is in a field observed by the 14-cm ASAS-SN quadruple "Brutus" telescope with a 2-3 day cadence, typical for our all-sky survey. The largest flare of B2 1633+38 in the ASAS-SN data was discovered on UT 2015-01-14.64 at V~14.9 mag. This figure shows the complete ASAS-SN V-band photometry for this interesting object, spanning more than 1000 days. In the last three epochs ASAS-SN measured the following V-band brightness
UT Date V
2015-01-01.660 17.0
2015-01-09.654 16.2
2015-01-14.635 14.9
with the last data point significantly brighter than any previous ASAS-SN measurement.
