FH Serpentis (Nova Serpentis 1970) was a nova, which appeared in the constellation Serpens in 1970. It reached magnitude 4.4.[2] It was discovered on February 13, 1970 by Minoru Honda located at Kurashiki, Japan.[3][4] Other astronomers later studied this Nova, and calculated its distances based on the decay time of its light curves.[4]

Nova Serpentis was also observed by the NASA space observatory OAO-2 Stargazer, active from 1968 to 1973.[5]

The Nova was important for science because it was one of the first to be observed in multiple wavelength bands including, infrared, visible, ultra-violet, and radio.[3] One of the observations that stood out was that it became brightest in the infrared 100 days after it was first discovered.[3]
