原说明:
Jorgen Blom: "Five pictures of Comet Ikeya-Zhang taken near Stockholm from March 14 to April 22, all using a 300 millimeter lens and with exposure times varying from 4 to 12 minutes. One can see that on the last date, April 22, the comet's coma seems to have nearly doubled in size. In part this can be explained by the comet being much nearer Earth on April 22; the difference in distance between March 14 and April 22 is in fact about 74 million kilometers or half the distance from Earth to sun."
