Study 000450:

ACRONYM: eis:eitwave_obssns

HOP-180 SNS study

This study is intended to be run in areas located close to the outer edges of active regions
in order to detect the evolution of propagating EIT waves. The main aim is to study the
plasma motions below the EIT wave fronts together with plasma density diagnostics.

TARGET:		     Surroundings of active regions 
EXPOSURE TIME:	     45
RASTER:		     Sit-and-stare
SLIT: 	             2"
NUMBER OF EXPOSURES: 40
FOV:		     2"X512"
RASTER DURATION:     33m 11s
Volume:		     33Mbits

Pointing:
---------

Areas located not more than 150" - 200" from the outer edge of an active region.

Use/Instructions to planners:
-----------------------------

Run the observation in the following order:

1) Run eis:eitwave_context. No. of raster repeat is 3

2) Run eis:eitwave_obssns. Optimum number of raster repeat is 8 (or as many as possible)
   - total duration: 4h25m28s

3) Run eis:eitwave_context. No. of raster repeat is 3

Please chain the three runs.

Observation run-time: 4h37m34s
Total data volume: 270 Mbits (8 SNS runs of eis:eitwave_obssns)

4) Warning:
-----------

None
