  Photographic UBV magnitudes have been measured for this peculiar,
variable emission-line F supergiant on plates taken by Mr. K. Olofsson
with the Uppsala Southern Station Schmidt telescope at Siding Spring
Observatory, Australia. The results are, with an estimated error of
+- 0.1 magnitude:


Date             V       B       U
-----------------------------------
 9 Nov,1982     8.95    9.8    10.3
 9 Dec,1982     9.1    10.1    10.4
27 Dec,1952     9.1    10.1    10.6
-----------------------------------

 The unusually low value of U-B on 9 Dec. may be due to rapid
variations, as suggested by Welin (1981). The time lapse from the
termination of the U exposure to the: beginning of the B one was
about 15 minutes.
