From BAA bulletin:

A fascinating series of double and triple phenomena of Jupiter’s moons will be occurring throughout October. The coupled orbits of the inner three moons mean that their phenomena recur at intervals of one week plus a few hours. The events visible from Europe including the UK are transits of I + II, preceded by their shadows, on Oct.5 (02:38-06:05 UT), Oct.12 (see below), Oct.19 (06:25-09:54 UT), Oct.26 (08:37-11:46 UT). (Times are from the first appearance of two shadows on the disk, to the last appearance of two moons on the disk.) John Sussenbach has already provided a nice time-lapse movie of the first event in this series, on Sep.27/28.

The best event is on Oct.12, with the shadow of IV in transit along with the shadows of I + III. There will be at least 2 moons and/or shadows on the disk from 03:24-08:02 UT.

Two other series of similar events will be occurring this month as well, but at times visible from non-European longitudes:

Transits of I + II, preceded by their shadows:
Oct.1, 8, 15, 22, 29/30.

Transits of I + III, preceded by their shadows (with II entering eclipse in the meantime):
Oct.3, 10, 17, 24, 31.

See the BAA Handbook for full details.

Stellarium suggests that Jupiter and the moon will be about 2.5 to 3 arcmin apart on the 25th/26th of Oct.

And the clouds will be 1000 Arcminutes wide covering the sky :-)

I keep forgetting to throw mash at my screen to emulate cloud-cover. :D

I am beginning to think -is the triple shadow transit event on Friday 11th October possible to observe as an all night session at the Martello Tower at Sandymount?
If us Dublin Sidewalk Astronomers stay up through the night into Saturday morning, we could see this extraordinary spectacle. I certainly would be on for it. See what others think. Jupiter is also nearby double star Wasat (Delta Geminorum).
