se misca pe la 4"/min acum (si viteza creste), deci in jur de 25-30s.

Am facut si eu o mica animatie a cometei: http://www.youtube.com/watch?v=WwIyiwKghbs&hd=1
Cele doua imagini de la sfarsit sunt atasate.


Sa speram la ceva cat mai stralucitor

alex care este perioada animatiei? intre ce ore/minute?

[auriga]

este tinuta sub observatie si de Bruce Gary - aflati ultimele noutati aici http://brucegary.net/ISON/
un articol updatat recent (4 nov) de Sekanika Z. http://arxiv.org/pdf/1310.1980v4.pdf in rezumat: "In summary, although the performance of C/2012 S1 is close to anemic,
there still is no hard evidence that the comet is about to fall apart.
However, prospects of a spectacular show near perihelion appear now to
be less likely than ever before."

edit: stiri bune: http://www.orca.ulg.ac.be/TRAPPIST/Trappist_Main_Fr/Site.html raporteaza "While the activity was stable for about a month (we have started our Monitoring on October 12), the gas production rates have finally increased rapidly the last days ! They were multiplied by a factor 2 since about a week, and mostly in the last 3 nights."

Cometele sunt impredictibile, nici profesionistii nu stiu cu siguranta ce se va intampla dupa trecerea la periheliu. Sunt estimari de la ca se va dezintegra pana la mag. -8

Am incercat si eu sa fac o captura la ISON cu camera DMK21AU04AS, iata rezultatul. Mentionez ca este a doua cometa pe care incerct sa fotografiez, prima fiind Lovejoy acum cateva zile, deci rezultatele nu sunt la fel de spectaculoase ca al colegilor, mai ales ca este o camera planetara

PS: Cometa era vizibila in telescop, insa inca nu este prea luminos. Am gasit prin trial and error in ocular, pentru ca din cauza umiditatii mari, cautatorul era inutilizabil. Cu ajutorul unui laser am pozitionat telescopul cam unde trebuie si pe urma, m-am miscat cam 2 minute pana cand am zarit in ocular.

Se pare ca e in outburst:
"Very good news, TRAPPIST ISON production rates (all gas species) have been x2 in only 24 hours !
We now reach about 2E28 mol/s for Q(OH) at 10.000 km.
It looks like an outburst is going on, as the increase was not as fast the last 4 nights,
We now see also jets in OH bands same location as those of CN and C2.
AfRho from dust continuum is only rising a bit,
R and V broad band flux have also increased by factor 2,

We should be able to get images until Nov. 18,
but window is only 20 minutes now and comet below 15 deg"

Cred ca aceasta imagine confirma intr-o oarecare masura ca ISON are o activitate crescuta,ea dezvoltand o a 3-a coada:

Vesti bune din nou tot de la acelasi observator:
"To our suprise the change has been huge in the last 24 hours ! We are reaching 1E29 mol/s in OH, an increase close a factor 8 of the amount of gas released in space, since 24 hours !"

se pare ca a innebunit ISONU'
