2019 Great Red Spot Viewing Times

Post by Christopher K. » May 22nd, 2019, 1:45 pm

The Great Red Spot is manifesting amazing and shocking behavior. Outside margins seems to be peeling off--the South Equatorial Belt seems to be pulling material off of the GRS. Will this make the GRS smaller for a lengthy period, or will the material regenerate within a short period of time?

Soon, I'll attempt to adapt the Sky & Telescope predictions for GRS viewing availability to Baton Rouge viewing times. The guidelines...
*The list is limited to times when Jupiter is at least fifteen degrees above the horizon.
*The list is limited to times when the Sun is at least eighteen degrees below the horizon.
*Although S&T states the GRS is visible for fifty minutes before and after transit, I limit it to forty-five minutes to be conservative. (In other words, a maximum viewing session of ninety minutes.)
*Given the above, only GRS viewing opportunities that are at least thirty minutes long are included.

[NOTE: Today at 2pm CDT, NASA-TV will broadcast "Storms Across the Solar System".]

Remainder of June 2019

9 June = 3:53am to 4:25am / 11:44pm to 11:59pm
10 June = 12:00am to 1:14am
12 June = 1:22am to 2:52am / 9:45pm to 10:43pm
14 June = 3:00am to 4:29am / 10:51pm to 11:59pm
15 June = 12:00am to 12:21am
17 June = 12:29am to 1:59am
19 June = 2:07am to 3:37am / 9:58pm to 11:28pm
21 June = 11:36pm to 11:59pm
22 June = 12:00am to 1:06am
24 June = 1:14am to 2:44am / 9:48pm to 10:35pm
26 June = 2:52am to 3:36am / 10:43pm to 11:59pm
27 June = 12:00am to 12:13am
29 June = 12:22am to 1:52am
All times are Daylight (blecch!). These times assume the Great Red Spot will be centered at System II longitude 302˚. Jupiter remains in Ophiuchus throughout the month of June.
