Tohban Report 09/12/21 - 09/18/21 Tohban Name: A. Runov (updated 09/21/21) Special Notes ------------- 1. The data collection was according to the request: THEMIS-Conjunctions Other times: EL-A / OBO NA NA or SD up to a max of 6/day EL-A / IBO none requested NA only between 14-20UT EL-B / OBO NA NA or SD up to a max of 6/day EL-B / IBO none requested NA only between 14-18UT 2. Interesting EL-A and El-B observations during the strom main phase on 09/17 22:00 - 22:20 UT. THEMIS probes were in fast survey mode but duskward of the midnight (Y_gse of 9 RE). EL-A and EL-B observed energeic precipitation and IB at L_igrf ~4. The PS was ~12 degrees wide. 3. Dst and Kp values were not automatically generated. I used http://wdc.kugi.kyoto-u.ac.jp/dst_realtime/presentmonth/index.html to fill provisional hourly Dst values.
