New OMNI Data Book Now Available

Volume 10, Numbers 3 & 4, December 1994
by Joe King
NSSDC has just issued Supplement 5 of its Interplanetary Medium Data Book. This data book contains plots and listings of hourly averaged solar wind magnetic field and plasma parameters from 1988 through the end of 1993. In contrast to earlier data books of the series, this one contains data from only one spacecraft, IMP 8ัthe only near-Earth solar wind spacecraft operating during the years covered. The data are from the instruments of Ronald Lepping (GSFC) and Alan Lazarus (MIT). In a few years, the next data book will be issued with data from IMP 8 and the newly launched WIND spacecraft.

The data presented in the data book are from NSSDC's OMNI database, which is available electronically and, for data through mid-1991, on CD-ROM. OMNI now spans over 30 years, starting with the 1963 IMP 1 spacecraft.

NSSDC issued the original Interplanetary Magnetic Field Data Book and Interplanetary Medium Data Book in 1975 and 1977, respectively. The plots and listings of the latest data book were produced by Natasha Papitashvili, while on an extended stay at NSSDC. She had supported requests for earlier editions of the data book from her position at World Data Center B2 in Moscow.

Copies of the Interplanetary Medium Data Book (NSSDC/WDC-A-R&S 94-08) are available from the NSSDC Request Coordination Office by calling (301) 286-6695 or via Internet at request@nssdca.gsfc.nasa.gov.
