Jupiter Viewing, 2019

Post by Christopher K. » February 21st, 2019, 3:30 pm

Jupiter's opposition in 2019 occurs during the 9am hour on 10 June. Accordingly, the Jovian Opposition viewing at HRPO will be on Sunday 9 June from 9:45pm to 11:45pm. Jupiter will be in the constellation Ophiuchus and will be eighteen above the horizon. During this time all four Galilean moons (Io, Europa, Ganymede, Callisto) will be visible. Io and Europa will be initially quite close; the distance between them will grow during the viewing.

The event will have no admission fee and will be for all ages.

Due to HRPO hours being used for the Jovian Opposition on the 9th, there will be no regular evening viewing on Friday the 7th; HRPO will be closed on that date.

Many may have heard the exciting and distressing news that the Great Red Spot may be "unraveling". The GRS will not be visible during the Opposition session, but may be visible during other Jupiter viewing times at HRPO throughout the months of June and July.

Tonight, tomorrow night and Monday night are the absolute best nights for viewing Jupiter in 2019, due to its close proximity. End of astronautical twilight tonight is 9:43pm and viewing should be fine until midnight, when relative humidity reaches ninety percent.

At 10pm CDT, Jupiter will be twenty degrees up in the southeast, in the constellation Ophiuchus. This is the NOAA forecast for 10pm...
precipitation potential, 6%
sky cover, 25%
relative humidity, 82%
temperature, 27˚C
heat index, 29˚C
surface wind, NW 5 km/h


Danko's Clear Dark Sky states that at 10pm the transparency rating will be "poor" (1 out of 5) and the seeing rating will be "average" (3 out of 5).

The 10pm rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

It's here! The Jovian Opposition of 2019 is here, and HRPO will be open tonight from 9:45pm to 11:45pm. The viewing, of course, has no admission fee and is for all ages.

This is the current NOAA forecast for that viewing time...
precipitation potential, 1%
sky cover, 22%
relative humidity, 70%
temperature, 25˚C
surface wind, NE 5 km/h

Danko's Clear Dark Sky states that both the transparency rating and the seeing rating will be "average" (3 out of 5) and the seeing rating will be "average" (3 out of 5).

The 9 June 2019 rating is...
EXCELLENT
VERY GOOD
GOOD
FAIR
POOR
BAD

The First Quarter Moon will also be available; Saturn will be glimpsed through the trees during the last fifteen minutes of the event. The front desk will have screenings of Jupiter-related videos from the Cassini, Galileo and Juno missions.

For best views, Jupiter should be at least thirty degrees off the horizon to avoid looking through a large amount of the Earth's atmosphere.

Below are select dates showing times at which Jupiter has reached thirty degrees altitude.
10 June = 11:04pm
13 June = 10:51pm
16 June = 10:37pm
19 June = 10:23pm
22 June = 10:10pm
25 June = 9:56pm
All times are Daylight.

Jupiter will be viewed Monday night at HRPO from 10pm to midnight during the peak of the Perseid Meteor Shower. It will be in the constellation Ophiuchus; all four Galilean moons will be visible (Europa and Ganymede on one side, and Io and Callisto on the other side). Telescopes will be retired at midnight so visitors can concentrate on searching for Perseids, the rate of which will increase after midnight.

Jupiter's shadow eclipses Ganymede between 8:25pm and 8:35pm tonight. Jupiter will be about twenty-five degrees up in the southwest at that time. That moon will remain eclipsed until after Jupiter sets. Happy Autumn!
