Giove è riapparso ormai da due mesi e mezzo nel cielo dell’alba. Il gigante quest’anno raggiunge un’altezza al meridiano di oltre 60°; si presenta quindi in posizione ottimale per essere osservato e ripreso, quando il seeing lo permette. Il mese di agosto, soprattutto la seconda metà, ha avuto caratteristiche di buona stabilità atmosferica. Ciò a permesso di fare buone riprese ccd con visibilità di miriadi di dettagli della coltre atmosferica del pianeta, L’uso di filtri, RGB per il colore ed Ir Pass per mostrare particolari profondi dell’atmosfera, portano a risultati davvero buoni, se si pensa tra l’altro che il pianeta è ancora lontano dall’opposizione del 29 ottobre. Questo particolare (lontananza dall’opposizione) costringe l’osservatore (aimè) a fare levatacce attorno alle 5 del mattino, se si vuole il pianeta ben alto, fatica comunque ampiamente ripagata, come potete vedere dai risultati che allego. Da notare ad es. nella ripresa Ir del 21 i partcolari visibili su Ganimede! Altro elemento interessante quest’anno, la completa ricomparsa della SEB (Sud Equatorial Band), completamente “scomparsa” l’anno scorso.

    is right. The PJ AND Susan Hernandez are classless, cleesuls, ghetto material. For the civil service titles, Court attendants (not real officers) are not protected under civil service law. Then the Clerk title was opened to all, no test needed, then the famous Analyst title was begun, so anyone with that title can be hired at any salary, and coincidentally fired with no Civil Service protection. So when people get laid off and they have many years on the job, expect no help, they want to protect all the newbies, how do you say that is Spanish? All the Unions are in Bed with OCA, not just CSEA, but Dennis Quirk and all his sidekicks, the pathetic SCO Union, and the Clerks Unions, the Lawyers Association, one is no better than the other. People are right this is a losing battle unless someone has the balls or is cunt enough to speak out loud not hide on this website. You also had to hear that Lippman soundpiece saying he was sorry but the Court Family had to have lay offs. They certainly are family in the AD1 with Papi Gonzalez leading the way. I may lay in his office with my legs spread open and see if a Line 23 comes my way, it seems to have worked for Maria Matos at Comm. Charc. Fitness, Manzanet-Daniels Chambers (ex girl-friend) and her family, Max and his sister in the PJ’s Office, who leaves for his Yankee job these days. And 1 part time vulgar mouthed deputy clerk, Elba Castro. Who loves to talk about her tits and ass. The AD1 has sunk to a new level of ghetto Bronx no nothings. They are the very people we all moved out of the bronx and headed North. Good Luck to all of you who are left behind. Freedom is great, we got out just in time………..
