Dear Kato-san,
Concerns: SN1993J upper limit on March 25.60
In the list of magnitudes of SN1993J in M81 you have included an upper
limit of 17 mag in the R band obtained on March 25.60 UT at Kiso Observatory
with a CCD on the 105 cm Schmidt telescope, taken from IAUC 5737.
However after obtaining better magnitudes for the comparison stars,
Dr. S. Yoshida and myself have now estimated an upper limit of about 18 mag
for SN1993J from our CCD image.
Could you please update this entry in your list of observations?
Thank you in advance,
Best wishes,
