A couple of zonds, VENERA-13 and VENERA-14 have been launched with a 5-day interval. Most time on cruise phase, spacecraft had his main axis X fixed towards Sun within <15(?) degrees accuracy and it was spinned around this axis with up to 1(?) hour period. ++Instrument: *.1 +++Name: ASP-8M +++PI: Dr. Nickolay N.

There are five sensors: two thick SSD (Si), ~500 microns, (D1,D2) and two thin SSD (Si), ~50 microns, (D4,D5) and one gas-discharge counter (D3). D1 and D4 are directed sunward along main axis X of the spacecraft; D2 and D5 are directed to the opposite side; D3 is on the sun side but under the spacecraft body's shell (~1 g/cm2 Al). View angle of each SSD sensor is as wide as +-30 degrees. Spacecraft memory is used for data storing; 20 minute time resolution is supplied as maximum. D1 and D2 have 80 minute time resolution. All sensors measure flux intensity continuously. +++Publication: *.1 ++++PublicationRef: S.N.Vernov, et al., "A study of characteristics of proton fluxes measured on SC VENERA-13 and VENERA-14", (in Russian), Kosmicheskie issledovaniya, 1983, v.21, 13, pp. 449-453; +++Publication: *.2 ++++PublicationRef: S.I.Ermakov, N.N.Kontor, G.P.Lyubimov, N.V.Pereslegina, V.I.Tulupov, and E.A.Chuchkov, "Case analysis of proton fluxes in the interplanetary medium using data from SC VENERA-13 and VENERA-14", (in Russian), Kosmicheskie issledovaniya, 1983, v.21, 13, pp. 466-475; +++Publication: *.3 ++++PublicationRef: S.I.Ermakov, N.N.Kontor, G.P.Lyubimov, N.V.Pereslegina, V.I.Tulupov, and E.A.Chuchkov, "Variations of Solar Proton Anisotropy on November 10-11, 1981", 18th Cosmic Ray Conf., Proceedings, 1983, v. 4, pp.162-164. +++AcknowledgingTo: TASPD SINP MSU +++DataSet: *.1 ++++ID: VD ++++StartDate: 81/10/31 ++++StopDate: 83/04/12 ++++TimeResolution: 20 minutes ++++ApproxVolume: 1.5 MB ++++DataSupportContact: Dr. Nickolay N.
