Solar Eclipse July 02, 2019

 SOHO: EIT and LASCO Observations Plan

 Update: July 02, 2019

Science teams can request LASCO and EIT support for their individual observations. Please look over the information below regarding the Eclipse program.  If there are special observations or timings that you require, please send us an email to the LASCO Planner address below.  Be sure to include your name, time of totality, and your observation request.


Once we receive your request, we will add your information into the observation program.
Special requests are listed by the Observer as shown below.

Observation plan summary. 

 Eclipse observations are interleaved with the daily synoptic observing program of the EIT and LASCO instruments.

The synoptic program consists of C2 and C3 full field full resolution at a 12 minute cadence.
EIT synoptic sets in the 4 wavelengths are daily at a 12 hour cadence executed at 01:00 and 13:00 UT.

Supplementary Eclipse observation support.
