The long-period variable HV 2379 in the Large Magellanic Cloud has been found to be a carbon star with exceptionally strong C2 bands and very unusual JHK colours. Around 1981 November, the star faded by ≡1.5 mag at K, and J-K increased from ≡1.6 to ≡4.8. The authors interpret this fading and reddening as due to the ejection of a shell; the nature of HV 2379 and its shell are discussed.
