A star in Norma was 2.3 times brighter on one NEOWISE visit in 2017: a test for Gaia DR4

Found blind in Oddsky hunts H-0008/H-0009: x2.3 in both W1 and W2 on 2017 Aug 12, every other visit quiet. No optical survey covered it; Gaia DR4 is the second instrument.

Claims

C1 [observed] NEOWISE on 2017 Aug 12: x2.3 brighter in both W1 and W2 than the star's median; every other visit quiet. No optical survey covered the event. Found blind by hunts H-0008/H-0009.
C2 [observed] A Gaia G 17.6 neighbour 3.2" away carries 73% of the target's G flux inside the NEOWISE beam, so the brightening may belong to it.
