1. Introduction

The aim of this document is to give an overview of the activities performed during the total solar eclipse on November 3rd 2013 and to summarise the outcome in terms of material production and response by the general public.The document is divided into two main sections: the first one is dedicated to the organizational aspects and initiatives that GLORIA setup for the event, while the second part is dedicated to the technical aspects of the live broadcasting.

1.1 Responsibilities

This document is under the responsibility of the WP2 coordinator, i.e. INAF (deputy IAC). The technical report included here is under the responsibility of Alejandro Galtier Hernández, CEO of CanarCloud (www . canarcloud . es ) which is the private contractor in charge of the dedicated infrastructure deployment and supervision.

2. The Event

After nearly a year without total solar eclipses (the last took place on November 13, 2012) on November 3rd, 2013 the shadow of the moon touched the surface of our planet again (Fig. 1). It was a hybrid solar eclipse, which means that in some places of the occultation strip an annular eclipse was observed, while in others a total eclipse was observed. Actually, the eclipse began as an annular and finished as a total. The 2013 hybrid eclipse was visible from within a narrow band, which crossed the North Atlantic and equatorial Africa (Fig. 1). The partial eclipse was also observable from southern Europe. About 31% of the solar disk was hidden as seen by viewers in the Canary Islands, while in mainland Spain the occultation was in the range from 7% in the South to 1% in the North. In southern Italy or Greece the occultation was 5% and 6% respectively.

Figure 1: Full band (purple lines) of the eclipse of November 3rd, 2013 as reported by NASA. The green marker indicates where the maximum duration of the eclipse happened. The observation point of the expedition was at Lake Turkana, north-west of Kenya.

3. The Expedition

The expedition was made in collaboration with Shelios Association (shelios.org), responsible for the planning, logistics and execution of the expedition. Collaboration for the satellite communications came from The Army, Canary Command and for the transport logistics from Tuareg Viatges.

GLORIA chose the northeast of Kenya on the eastern bank of Lake Turkana, on the southern edge of the National Park Sibiloi as the final destination for the observation (Fig. 2).

The expedition and retransmission was coordinated and directed by Dr. Miquel Serra-Ricart (GLORIA astronomer, IAC manager of the Teide Observatory).



Figure 2: Observation point of the expedition (G1). The blue line marks the center of the band of totality while the red lines are the northern and southern limits of the totality.

3.1 The team

The expedition team was composed of 16 people. The GLORIA group was composed of:

● Dr. Miquel Serra Ricart: Coordinator of the broadcast and project leader. Astronomer at the Instituto de Astrofísica de Canarias (IAC) and Administrator of the Observatorio del Teide.

● Mr. Esteban González, Fernando Serena & Francisco Sánchez: Engineers from the Universidad Politécnica de Madrid (UPM). Broadcasting & social networks.

● Dr. Paul Cox, Astronomer from Slooh Telescope (slooh.com). English version comment/script.● Mr. Javier Fernandez Calvillo Burgos, The Army, Canary Command, Satellite communication.

Additionally there were two external people from Shelios (J.C. Casado) and SECAT (D. Hernández) associations (both private non-profit entities).Mrs. Liliana Elzbieta collaborated on the Polish version of the broadcasting.Their travel started on October 30th 2013 with arrival in Kenya on October 31st. The base camp for the live broadcasting was on the coast of Turkana Lake inside Sibiloi National Park (Northern Kenya). They left Kenya, after the eclipse, on November 7th, arriving in Spain on November 8th.

The equipment that was used in Kenya was:● Telescope (Borg 77 EDII) and a mount (Astrotrack) with a sidereo/solar guider.● 6 cameras including 2 x Canon 5D-Mark II + 1 Mark III (photos/video) at the focus of the telescope (+

CanonUtility soft).● DBK cameras model 41AU02.AS with 200mm tele-lense.● Webcam (GoPro HERO2 with Teradek Cube 255) for presenters (Miquel&Paul).● 3 x Apple Computer (realization and coordination via CamTwist/Adobe Encoder for MAC OS).● Satellites (Explorer 700, Explorer 500, Turaya) and connection (BGAN X-Stream - 350 kbps - 43 Kps).● Telephone Connection (voice and data).● 2 x Wireless microphone (Samson) and a mixer/recorder (Handy H4n).



3.2 Weather conditions

Unfortunately the weather conditions were not optimal at the observing site. At the moment of first contact (C1) a big dust storm with strong winds and rain arrived at the camp site. Only some images, using manual cameras and lenses, were taken.

4. Educational activity

Due to the dust storm, we could not get good quality data of the environmental parameters that would have allowed us to perform this activity correctly. So we encourage users to do the activity with the data already taken during the previous eclipse of November 13th, 2012.

4.1 Web tool

To encourage and help as many users as possible to perform the activity, we implemented an interactive web tool that displays the solar radiation and temperature recorded during the eclipse of 2012 and allows the users to input with the cursor their guessed values of the minimum of brightness and temperature (see Fig. 3). The data are stored into a database and the statistics are accessible. The newly inserted data are compared with the previously inserted ones (see Fig. 4). Once a reasonably large number of inputs are collected, we will prepare an online public report that summarizes the results. Statistics and comments will also be included.The web tool uses web 2.0 technologies and is accompanied by a text and video tutorial. It is available in eight different languages (see Fig. 3 and gloria - project . eu / eclipse - meteo / ).

5. Multimedia material

5.1 Before the event

In addition to the educational activity, various multimedia material were prepared for this unique event:● Dedicated web pages were prepared in all the GLORIA languages. See, for example, the English version

of the event web page under the “Expeditions” menu (gloria - project . eu / gloria - live - events - expeditions / solar - eclipse -2013/ ) and the related sub-pages (see Fig. 5).

● An advertising video with subtitles in the various languages was prepared and published on the GLORIA YouTube channel (also linked on the website). See http :// youtu . be / rOiOdatL 7 ow . About 31,000 views to date.

● A press-release in all languages was prepared and distributed (see gloria - project . eu / gloria - live - events - expeditions / solar - eclipse -2013/ for - the - press / ).

● The webcasting reference website live . gloria - project . eu was updated and made accessible both in English and Spanish.

5.2 During the event

From Turkana lake the total duration of the eclipse was 2h 14m (13:13-15:27 UT) and the broadcast was made in two ways:

1) Live: with a total duration of 15 minutes coinciding with the peak in Europe and the second (C2) and third (C3) contact. From Turkana, astronomers (Serra-Ricart & Cox) provided Spanish and English commentary. Additional live comments were provided in Polish by Mrs Liliana Trzpil.

Connection 1: Maximum in Europe - November 3rd, from 12:00 to 12:05 UT (13:00 to 13:05 CET).Connection 2: Second and third contacts - November 3rd, from 14:20 to 14:30 UT (15:20 to 15:30 CET).

Note: Local time in Kenya was from 17:20 to 17:30 (3rd of November).Note: UT– Universal Time; CET– Central European Time.

2) Sequence (Time-lapsed). From the 3rd of November at 13:00 UT (14:00 CET) the image of the Sun was refreshed (partially eclipsed by the moon) every minute.

During the event a test was held to translate the live broadcast and resend it to the YouTube channel. This worked



so well that it was used in the event itself. See http :// youtu . be / ImDDmLqXWMM - first part, http :// youtu . be / FAAmhuVE 7 Bw - second part.

More than 84% of the concurrent viewers during the live event were connected through the GLORIA YouTube channel. We counted a total of 26,859 viewers and a peak of 11,298 simultaneous users watching the live event.Moreover on November 3rd a total of 121.211 viewers accessed the GLORIA YouTube channel. Accesses were mainly from Poland, the United States and Spanish-speaking countries. For more information, see the deliverable document D9.3.

The announcement of the event triggered a discussion among Facebook followers that led to an increase of about 1000 subscribers.

5.3 After the event

Activities started soon after the end of the transit include: video production, time-lapse animations, image collection, statistics collection, etc. See for example the YouTube channel youtube . com / gloriaproject and the dedicated Flickr album . These material will be used to advertise the project i schools and associations as well as to promote the educational activities. These activities will continue in the coming months.

The GLORIA website access statistics and demographics are shown in Figure 7 and 8. During the period 28 Oct. - 8 Nov. we received 39,088 visits (31,433 unique) and 79,740 pageviews. Statistics about the live webcast are reported in the technical section below.

Chile:The last GLORIA expedition to Africa had a strong impact among mass media in Chile and the other South American countries, in particular in México. The GLORIA press coverage archive lists the relevant media where the news appeared.University of Chile journalist D. Azocar was very active in spreading the word among more than 250 Facebook groups (all of them related to astronomy, physics and science in general). He also contacted almost 150 “opinion leaders” through Twitter, mostly from Chile, Argentina, México, Colombia and Uruguay. News about the expedition and the eclipse’s streaming also appeared on the University of Chile web portal and other Chileans websites. The list of newspapers, TV channels and web portals that reported the news include: El Universal Newspaper (México), Televisa (TV Broadcast, México), La Nación (Argentina), Telefe Broadcast (Argentina), El Mercurio Newspaper (Chile), La Tercera Newspaper (Chile) and El País Newspaper (Uruguay). The statistics shown in section 5 clearly demonstrate the success of the advertising campaign.

Czech Republic:A press release published on the Czech Astronomical Society webpages (http :// www . astro . cz / article /6024 ). A short report, including an image from Kenya, was published on the main page of the Czech Technical University (CTU) in Prague (http :// www . cvut . cz , Fig. 10). The broadcast was also announced to the students of secondary schools during their visit to CTU.

7. The event in the press

The Total solar eclipse event had a big media impact and articles about it can be found on almost any media source, especially on the web. We have selected and saved a sublist of more than 80 of them in the GLORIA archive. It is accessible from gloria - project . eu / press - coverage / .

8. Technical report: Infrastructure

8.1 Portal Web Broadcast

The infrastructure deployed by CanarCloud (www . canarcloud . es ) was based on a VMware vSphere Cluster 5 (www . canarcloud . es / vmware / ) based also on an Intel Nehalem architecture interconnected to a centralized RAID storage system capable of supporting the load of the several thousands of requests on the website of the broadcast along with a DNS balancer. This interconnected all web instances, both physical and virtual of all collaborators, ensuring an equitable load sharing of all website visits among all instances (see Fig. 12).


http://www.canarcloud.es/vmware/













http://gloria-project.eu/press-coverage/











Figure 12: Overall broadcasting infrastructure used for the live webcasting.

Given the high expectations and in order to reduce the time and rate of transfer of resources included in the website (logos and static images, javascript and style files, etc.) a Proxy was implemented with a cache of static content in a CDN service by gloria.cdn.canarcloud.net.

The operation of this architecture is as follows:

● Clients make the request to the web portal of the broadcast that should be designed so that the size (in bytes) is minimized.

● A Load Balancing system decides which of all servers that form the cluster will serve every request that comes in terms of the policy implemented.

● The client is served by the server selected by the load balancing system.● When the client loads the page directly in his browser, gloria.cdn.canarcloud.net is asked to load static

content through the proxy, which provides a minimum of 3h cache.

9. Technical report: web contributors

Assistance was requested from public and private institutions, associations, foundations, etc. to aid in the dissemination via Internet of the gateway of the broadcast (live . gloria - project . eu ) in an attempt to prevent the collapse due to a massive confluence of requests.

9.1 Basic Web Collaborators

In this type of collaboration, the institution, organization, association, etc.. temporarily attached a machine or set of machines to the cluster property proposed. This machine (or machines) that are grouped together, served web portal with all the contents of the broadcast.
