Thank you so much for all who helped us to receive.

[現在のSPROUTの状態]/[Current status of SPROUT]
現在SPROUTはCW(通常モード:G3/437.525MHz)運用を行っています.
Current status of SPROUT is CW(nomal mode:G3/437.525MHz).

[次回の運用内容]/[Next Operation]
夜間の4th,5thパスは,FMダウンリンク(437.600MHz/AFSK)を行います.
The Nighttime 4th and 5th operation is going to operate FM downlink(437.600MHz/AFSK).

[運用のお知らせ]/[Operation info.]
次回のSSTV運用は1/11(日)を予定しています.
We will operate SSTV downlink(437.600MHz) on 1/11(Sun).

[運用結果]/[Operational results]
2015/1/10 昼間の運用を3パス行いました.
2015/1/10 Daytime operation: We have conducted 3 operations.

1st:CW:S0[dB] FM:–[dB] Digi:–[dB] Bus Voltage:-.—[V]
2nd:CW:S3[dB] FM:S5[dB] Digi:–[dB] Bus Voltage:4.823[V]
3rd:CW:–[dB] FM:S4[dB] Digi:–[dB] Bus Voltage:-.—[V]

1st:CW運用を行いましたが,ノイズが多くデコード出来ませんでした.
2nd:CW運用にてバス電圧4.823[V]を確認後,FMダウンリンク(AFSK/437.600MHz)を行いました.
3rd:引き続きFMダウンリンク(AFSK/437.600MHz)を行いました.

1st:We couldn’t confirm bus voltage because of the noise.
2nd:We confirmed bus voltage 4.823[V] at CW operation. Then, we have operated FM downlink(AFSK/437.600MHz) .
3rd:we have operated FM downlink(AFSK/437.600MHz) continuously.

次回のパス情報は以下のようになります.
日付 || 時刻:AOS ~ LOS || 可視時間 || 方位角: AOS時 ⇒ LOS時 / 最大迎角時 || 最大迎角
Date(JST) || Time of AOS ~ LOS || Duration || Azimuth at AOS ⇒ LOS / MEL || MEL
2015/01/10 || 22:32:25 ~ 22:44:39 || 00:12:14 || 143.7 ⇒ 359.8 / 072.2 || 31.1
2015/01/11 || 00:08:56 ~ 00:20:22 || 00:11:26 || 202.5 ⇒ 328.9 / 266.3 || 18.1
