Overview of a coronal hole-associated high speed stream, July 26/27 2003.
An example of a coronal hole-associated high speed stream that has corotated at least 5 times (Dec 1999 to Mar 2000). The rotation period is close to 27.3 days, which is the synodic solar rotation period (i.e., the solar rotation period as viewed from the Earth).
A possible shock-pair: a coronal hole-associated high speed stream appears bracketed by a zone 4 forward (17 May 1999, 2354 UT) and zone 1 reverse shock (18 May 1999, 1911 UT). An overview plot shows the timing of the Forward and Reverse shocks relative to the Stream Interface region.
An example of a coronal hole-associated solar wind flow (beginning at about 0800) on 30 Nov 1997. The solar wind Fe charge state distribution in this coronal hole is available from our SWICS sensor on the ACE spacecraft.
An interesting event at 2203UT on 13 October 2016.
Possible heliospheric current sheet crossing at 2000 UT on 2 August 2016.
Possible heliospheric current sheet crossing at 0058 UT on March 18, 2013. (WIND MFI plot)
Another possible heliospheric current sheet crossing at 1410 UT on April 2, 2012. (plot with WIND MFI and ACE MAG data)
Several X-ray flares and shocks from sunspot AR1429 in March, 2012
Possible heliospheric current sheet crossing at 0753 UT on Nov 30, 2011. (plot with WIND MFI and ACE MAG data)
An interesting structure observed on 22 Feb 2000.
