          EPSILON AURIGAE: B V R I J H K PHOTOMETRY

  We have made photometric measurements of the peculiar binary system
epsilon Aurigae at a number of epochs during the current eclipse. The B,V,R,I
measurements were made with a 14" Celestron telescope using a solid state
photometer from Thaltej near Ahmedabad (23d03' N, 72d30' E). Measurements in
the infrared J, H, K bands were made with the 40" telescope of the Uttar
Pradesh State Observatory at Nainital using a liquid nitrogen cooled InSb
photometer. Results are listed in Table I.

 Errors in the magnitude measurements in all the filters are of the order of
0.05 mag.
  We note from Table I that the eclipse depths in the infrared are similar
to those in the  visible and the third contact occurred much later than the
predicted  date January 9, 1984. These results are in agreement with those
reported in Hopkins and Stencel (1984).
