PROBA2 Partial Eclipse Observations - 13-Jul-2018 and 11-Aug-2018

Two partial solar eclipses will be visible this summer: one on 2018 July 13 and another on 2018 August 11.

The majority of the eclipse in July will take place over the Pacific and Indian Oceans, and a very small fraction above the southern Australia.

The eclipse in August will be visible from northern and eastern Europe, northern parts of North America, and some northern and western locations in Asia.

The PROBA2 satellite will also observe the two partial eclipses, on July 13, between 01:33 and 01:47 UT, and between 03:00 and 03:19 UT, and on August 11 between 08:29 and 08:49 UT, and between 10:21 and 10:45 UT. Additionally, for each of these eclipses, the Moon will appear one more time in the field of view of the solar instruments onboard PROBA2, SWAP and LYRA, without obscuring the solar disk.

The movie simulating the SWAP observations on July 13 can be found here and the one simulating the SWAP observations on August 11 can be found here.

SWAP Data of the Eclipses

During the two eclipses, SWAP will observe the Sun at high cadence. Afterwards, we will produce our usual sets of calibrated PNG images (with logos and timestamp, with timestamp only, and without logos or timestamp) as well as movies of the event. Below is a SWAP image of the eclipse on July 13. 

All the movies and images of the July eclipse are now available at this link, and the ones of the August eclipse will be provided at the following link. These directories also contain the SWAP images with the largest part of the Sun occulted by the Moon, as the one shown above.

LYRA data of the eclipses

LYRA will use a second unit in parallel to the nominal one during the eclipses. On July 13, the usual backup unit 3 was switched on. The peak around 03:07 was caused by a maneuver of the spacecraft.

On August 11, we will use in alternance units 1 and 3 as the second unit.

Data Use Policy

All PROBA2 images and movies used in outreach and the media should be credited to "ESA/ROB". Additional information about the terms of use for PROBA2 data is available on the PROBA2 website.

Contacting the PROBA2 Team

All requests for media comments, data assistance, or planning requests can be directed to the SWAP and LYRA teams via swap_lyra@oma.be.
