Spacecraft : Select a planet/spacecraft to connect magnetically to the Sun
Coronal Magnetic field : Select a coronal model to connect photosphere-upper corona
Interplanetary magnetic field : Select solar wind model to connect upper corona - planet/spacecraft
Propagation mode : elect the type of propagation either instantaneous (EM LAG) or at a constant solar wind plasma speed (SW LAG)
Time & Date : Choose the date you like and then select between 4 different times : 00:00; 06:00, 12:00, 18:00.
You cannot choose a date before 2016-01-01 and past 10 days from current date.
If you're using a SAFARI browser, you need to enter the DATE manually, following this format : YEAR-MONTH-DAY
YEAR is four digits (like 2019), MONTH is two (like 05) and DAY two digits also (like 23)
Here is a full and functionnal example : 2019-05-23
Try different TIME for a DATE, sometimes there are some maps but not at the TIME you think.
