THEMIS Observations May 99 coordinated with SOHO, Yohkoh, Trace +GB obs. ************************************************************************** (P. Mein and C. Briand: observers) This is a preliminary list (approximate times, data not yet processed) Mode MSDP (Multichannel Subtractive Double Pass) 16 wavelengths in each line profile Polarisation analysis (all data): I+V/I-V Lines: Halpha and NaD2 (simultaneous), CaII8542, NaD1 For most of the scans, the field of view is 4arcmin * 4 arcmin The duration of each scan is typically 9mn. The best time resolution is about 14 mn in case of successive scans. The times of the list do not take into account the gaps between scans (pauses due to bad seeing or instrumental problems). AR = Active Region QS = Quiet Sun The centers of the scans are not always the centers of AR. Date times Target Coord.
