Dear ILRS Colleagues,

QZS-1 tracking campaign will start next week.
We re-consider details of QZS-1 tracking campaign.
We would like to modify our plan.

We hope to extend QZS-1 tracking campaign, that is,

Period
(old) From 30/Nov. To 7/Dec.
--> (new) Extend 10 days
From 30/Nov. To 17/Dec.

Core Time
(old) 9:00 -- 9:20 (UT)
12:00 -- 12:20 (UT)
15:00 -- 15:20 (UT)
18:00 -- 18:20 (UT)
21:00 -- 21:20 (UT)

-->(new) Extend to daylight tracking,
Try 4 hours interval,
0:00 -- 0:20 (UT)
4:00 -- 4:20 (UT)
8:00 -- 8:20 (UT)
12:00 -- 12:20 (UT)
16:00 -- 16:20 (UT)
