Torus Tip prediction format:

· UT Date and time of when Io is at elongation (furthest from Jupiter, thus in the center of its Torus Tip)

· The “Tip” column will tell you which side of Jupiter Io is on

· The times of the expected start and stop of extinction and the minima is given

· All predictions are estimates and are likely accurate to within 5 minutes UT

· Image Io as long as possible during these torus Tip transits, and be sure to include data outside of these predicted times (a minimum of 30 minutes or more when possible) to provide a baseline

· Keep at least one other moon of Jupiter in your field of view to use as a photometric reference, preferably Europa or Ganymede

· As with all photometry do not overexpose nor under expose your images

· Video imaging seems to be the easiest way to document such lengthy photometric runs

Sample predictions:


Date Time UT	Start	minima	elongation	End	Tip
2012-Nov-28 23:31	21:59	23:09	23:31	2:15	E

Date Time UT	Start	elongation	minima	End	Tip
2012-Nov-29 20:44	18:00	20:44	21:06	22:16	W

Standard Nomenclature:

Dates and times are UT

“Event type” = (A) B (C)

Where:

A = object in front

B = event, where:

e = eclipse

o = occultation

x = dimming by atmospheric extinction

u = dimming by flux tube

C = object in back

Objects:

J = Jupiter

I = Io

II = Europa

III = Ganymede

IV = Callisto

Te = Eastern tip of the Torus of Io

Tw = Western tip of the Torus of Io
