It looks like five contrails were seen at Naruo-hama Park today, 4/4, at 12 noon.
(This information was provided by GOTO510. Thank you!)
Here it is↓

Five contrails at once is rare!
By the way, I looked up the saying “when contrails linger for a long time, it means rain,” and apparently it’s because the air is humid. That’s why it rains. On the other hand, when they disappear quickly, it means the air is dry. But how many minutes does “quickly” actually mean??
Did anyone else see the same contrails?
iroha sent us a photo too.

*GOTO510, thank you for the tip!!
