BAA Issues Report on EZ
1/30/2022

Dr. John Rogers at the British Astronomical Association has announced publication of their 7th report for the 2021-2022 apparition of Jupiter. This report highlight activity in Jupiter’s Equatorial region.

  •  Methane-bright patches in the EZ that are almost stationary in their CM III (L3) longitude
  • Bright plume outbreaks seen in the unusually quiet NEBs with two recent outbreaks happening December 19th and January 9th.

Don't Quit Yet!

We are a little over a month from Jupiter’s solar conjunction (Mar 5, 2022), so it is getting harder to observe the giant planet. But if you are fortunate enough to have a clear western horizon, your observations can be very important before we lose the planet entirely the Sun’s glare. We have seen before a situation where Jupiter emerges as a morning object a few weeks later sporting significant changes since it left the evening sky. Even though your observation may lack steady seeing and fine detail that is more easily captured at opposition, recording the state of large-scale features can prove useful.


Juno Spies Clouds Above Anti-Cyclone Storm

Don’t miss today's amazing image at APOD of one of the anti-cyclone white ovals captured by the Juno spacecraft during last month’s flyby of the giant planet. The photo resolves higher 50km clouds across the face of the oval as well as their shadow against the white oval cloud deck below.


Images Needed for PJ38

The Juno probe will be performing the 38th periJove flyby on Monday, November 29th. Observation of the planet in advance of this pass are requested, centered approximately on CM III longitude of 85°. We have posted some times on the events calendar to highlight times when US based observers, but people in other locations can use WinJUPOS to determine when that longitude is favorably positioned from their vantage point. Send your images or sketches to jupiter@alpo-astronomy.org for inclusion in our gallery and access NASA's Juno website to upload images to the Juno team.
