Abstract:
Recently we have successfully observed the lunar occulation of a carbon star IRC+20120 and a M5 star IRC+10241 with the NICMOS sub array at the 1.2m Gurushikhar telescope. The integration times were respectively 5 millisec and 3 millisec per sample in the broad K band. The interval between two integrations was ~ 16 millisec. FOV of the sub array was 10 arcsec x 10 arcsec. Details of the experiment and results are discussed.
