Ine Theunissen-Limpens report/s the discovery of a new astronomical transient.

IAU Designation: AT 2016jjh
Coordinates (J2000): RA = 09:51:54.456 (147.9769) DEC = -06:49:12.72 (-6.8202)
Discovery date: 2016-10-13 09:13:53.000 (JD=2457674.8846412)

Potential host galaxy: NGC 3035
Host redshift: 0.01455

Remarks: This transient was first discovered by Ine Theunissen while examining galaxy NGC 3035 in the Legacy Survey Sky Viewer here: http://www.legacysurvey.org/viewer?ra=147.9791&dec=-6.8229&layer=decals-dr5&zoom=15. Richard Nowell also took part in the discussion started by Ine Theunissen on the Galaxy Zoo website here: https://www.zooniverse.org/projects/zookeeper/galaxy-zoo/talk/1269/1203627.

Photometry
