1970-095A
The second Lunokhod mission, E-8 No. 203, was not launched until Nov 1970 following the first successful E-8-5 mission, Luna-16. The new flight was named Luna-17 and it landed on 1970 Nov 17, successfully deploying Lunokhod-1.
Details of the Luna-17 launch profile, given below, were revealed in Novosti Kosmonavtiki in 1995. The Proton separated on a suborbital trajectory. The first Blok D burn lasted less than 370s (NK implies 370s but I believe there was a coast period before the burn started; 200s or less would be more reasonable given known properties of the Blok D), and the second one 400s.
