However, I have one thought that might interest you. Your observation can now be performed in two ways: 1) Context, SNS * stop for 15 minutes * SNS, context or 2) Context, SNS, Context *stop for 15 minutes* context, SNS, context With option 2 you can have two runs on either side of the 15 minutes stoppage. As for your comment: > Nevertheless, as this second gap is in time period of the highest chance > for good seeing for DOT it would be good to know the exact timing > of the second contact (~9:30 UT): is it 09:15-09:30 or 09:30-09:45 or other > position of the interval in time ?

I have spoken to our planners in Japan and they will attempt to email you the day before and let you know the stoppage time as accurate as available to them so you you can plan the auxiliary data acquisition.
