Leonids 2002
- The Results
My short trip to Andalusia,
Spain lasted from November 16 (morning) till
November 19, 2002 (evening) with a primary focus to make
visual and photographic observations of the Leonids.
The objective of the visual observations was to
accurately determine ZHR (Zenith Hourly Rate)
profiles of the Leonids on the night of maximum
activity. I did not make upfront arrangements for
coordinated simultaneous photographic observations.
The
observing site
I intended to
observe from a small hotel, called Cortijo
Valverde, situated halfway between the
Andalusian villages of Alora and Ville
del Abdalajis (near 36°04' N, 1°02' W),
about a 1 hour drive from Malaga and the coast
line.
On the evening of our first
day at Cortijo Valverde (Nov 16/17), the
sky was clear, and this allowed me to do some
pre-checking on the observing conditions. The
area around the swimming pool of Cortijo
Valverde really would be an ideal spot to
observe the Leonids : no city lights at all,
in fact not a single light was visible in the
hills surrounding the hotel. In addition, the
air was very dry, so despite the strong
moonlight, the limiting magnitude was still
well above mag 5. |

The days before the
predicted Leonid maximum, Kathleen and I hiked through
some of the most spectacular landscapes of Andalusia.

The night of November 18/19 - storm night !
On November 18th, the
weather during day time was excellent. In fact, the
few clouds that were still present during the morning
and around noon, started to disappear as the evening
approached. So, expectations and hopes were very
high.
I did a final check of
the sky around 23h local time, before trying to catch
some sleep. At that moment, there were already some
thick clouds floating around. I got very worried.

I woke up around
01h30m local time to start preparing the
observing session. My intention was to kick off
the visual ZHR determination around 2h local
time (i.e., about 3 hours before the predicted
maximum activity). I went outside to check the
sky conditions and was deeply disappointed. Only
a small patch of the sky was still without
clouds (towards the direction of Leo).
The picture at
left was made around 1h45m local time, on
November 19th, 2002. I used an Olympus 3030-Z
digital camera. The exposure time was 16 sec.
The brightest object on the image is Jupiter.
Clouds are already dominating the sky. |

A cold front now was
quickly approaching and within 10 or 15 minutes, the
complete sky got covered. My hopes of observing the
Leonids were all gone. I
subsequently did regular checks of the sky conditions
between 2h and 5h local time, but around 4h30m local
time (half an hour before 'the moment supreme') it
started to rain intensively.
It stopped raining in
the morning at breakfast time ... I saw about 5
Leonids all together ...
A disappointing and
failed expedition from an astronomical point of view.
But in terms of hiking and sight seeing, this
definitely was a successful and enjoyable trip for
Kathleen and myself !
