January, page S-8, and July, page 104—In a story by Steven Shore for Physics News in 1983 and a in a subsequent letter by Shrinivas Kulkarni, respectively, an error was made in identifying IRAS, launched in 1983, as the first satellite to ‘discover’ a comet. The SOLWIND instruments detected three sungrazing comets in 1979 and 1981 via the P78-1 satellite. Additionally, the comet that was detected by IRAS was incorrectly identified in both the original article and the subsequent letter; its correct name is IRAS-Araki-Alcock 1983d.

July, page 105—In the letter by J. Rand McNally Jr on fusion criterion, the central temperature T 0 for Alcator C should be given as 1.5, not 12.5 keV.
