September 21, 3006 — Quiet skies, stormy skies…
It all began with a Kreutz group comet spotted by expert SOHO/LASCO (and SOHO/SWAN) comet hunter, Rob Matson, late at night on September 17th. Shortly after discovery, SOHO entered into a reasonably long data gap that lasted into most of the next day. During these data gaps, even though we do not have "real time" contact with the spacecraft, data from the instruments is recorded on board ready for downlinking at the next time of contact. I often give advice to comet hunters at times like this to watch the spacecraft contact times and await the influx of new data. Clearly, Rob was following this advice when the data began to flow because, in the space of 42 minutes and 14 seconds, he reported another four Kreutz comets in the LASCO C3 and C2 fields of view! By the time a few other comet hunters had rejoined the hunt, Rob had already cleared up. This was the first time that five Kreutz comets were visible in C3 in less than twenty-four hours, and certainly the first time a comet hunter has found five comets in such a short period. Congratulations, Rob!
Pictured opposite are three of the five aforementioned Kreutz comets (click for a larger image). The other two (SOHO-1189 and SOHO-1191) were a little way ahead of these, so I chose these three as a nicer image. You can see a short tail on SOHO-1190, and (even though it was the brightest of the five comets) a much shorter one on SOHO-1192. SOHO-1190 had no noticeable tail at all.
