To everyone
We could observe the site of G impact at 11:28(UT) with 1.8 m Bohyunsan telescope. CH4 filter was equiped on the telescope. The size of the G area is comparable to that of the Great Read Spot.
We also could observe the G site with 61 cm Sobaeksan telescope with CH4 filter and no filter at the same time of the observation of Bohyunsan. In no filter observation, the dark image at the G impact was seen.
We also detect the G image with 20 cm telescope at Daeduk.
Sincerely yours,
from bgkim@hanul.issa.re.kr
