My initial thoughts after successfully observing the occultation last night:

Through hazy skies, we (myself and Alex Pratt) had a successful observation of the occultation of Betelgeuse from just south of Alicante, near the airport.
My personal thoughts from visually observing it are:

Skies consisted of variable levels of haze, which made the observation more challenging (and head-wrecking) that I would have liked.
The dimming was not sudden like a typical occultation, but rather quite gradual which appeared to take approx 2-3 seconds.
The star appeared to dim by approx 1 to 2 magnitudes – quite noticeable.
The rise was more difficult to detect visually due to the haze.
I was expecting it to remain at its faintest magnitude for a period of time, and was surprised to see it brightening almost immediately after reaching minimum magnitude.
