- Sungrazer comet entering the C2 FOV on 2005/09/29 at ~ 00:20 UT (bottom right). It disappears behind the C2 occulting disk at 05:06 UT. - Sungrazer comet starts to be visible in the C3 FOV (bottom right) on 2005/09/28 @ ~ 18:42 UT. - EIT CME watch in 304 on 2005/09/28 between 07:19 - 19:25 UT, in support of filament observations (#7155). SOHO KEYHOLE #10 telemetry period: Aug 31-Sep 28, 2005. During the Telemetry Keyhole LASCO was in improved synoptic cadence of C2 at 12 mins cadence and C3 at 30 mins cadence, including daily orange/blue filter fielding images.
END OF KEYHOLE. 01:54 UT ES East Initially diffuse front develops as a big and asymmetric bright loop front (apparently a complex two-component front). By 04:54 UT the whole event spans from the N Pole up to the S Pole (on the eastern hemisphere). Pseudo-continuous outflow all across the eastern hemisphere abd some faint expanding loop fronts on S, all along the day. EIT 195 images do not show signatures of a frontsided (nor limb) prior to the time of first appearance in C2. 06:54 UT E Limb Bright elongated front in the aftermath of previous event. 11:30 UT S West Narrow an elongated loop-like structure. 17:29 UT S West Very faint and elongated loop front. 18:13 UT EN East Bright loop front preceded by a faint and diffuse front. Extremely faint expanding extensions up to SE. 19:43 UT S East Faint and elongated loop front.
04:54 UT E Limb Faint elongated loop front. 05:30 UT S West Blob-like front. 08:30 UT WN West Faint ragged loop front brighter to N. Last C2 image available by the time of writing: 12:06 UT.
