Quote:At present, to truly be similar in behavior with C/Seki-Lines, ISON would be developing an increasingly small, dense , very bright condensation within the coma. Likewise, the intensity and length of the tail(s) would be rapidly growing , just as we saw in the case of 2011 W3 Lovejoy immediately following its perihelion.BrooksObs

Quote:The SOHO coronagraph sensors regularly record solar wind particles hitting the silicon as bright spots. Just be aware of this. Watching a CME coming head on to SOHO is awesome - it ends with a dense "snow storm" as hundreds of high energy protons and electrons pepper the sensor
Quote:I am not certain if this is noise or a star, but the latest C3 shows a bright speck that was not present in previous frames.And it's in the corresponding vicinity where the nucleus should be, on ISON.

Quote:When postulating multiple nuclear fragments, consider the image scale/resolution, the distance to the comet, and the time since potential break up. A ~2km body which breaks up will have its parts separate at a very leisurely pace. If we suppose a velocity range of, say, 10m/s (which might be on the fast side), that's 864 km/day. These images resolve to what, 10,000 km/pixel (and probably worse) at the solar distance? It would take some time for discrete bits to be separately resolved in such images. Moreover, tidal disruption tends to spread the particles into a string oriented pretty much along the orbit, and not in a randomly scattered grouping.

Quote:But I will say that my info is important since it allowed me to not only predict that Ison would survive fully intact, but also predict when the tail/coma would fade before perihelion, and when it would rekindle after perihelion (at + or - about 10 minutes), and predicted that they would claim it disintegrated just to eat their words later.

Quote:"The dust tail of the comet is now divided into two parts," explains Hermann Böhnhardt from the Max Planck Institute for Solar System Research. According to Böhnhardt, the part of the tail that is pointing towards the sun consists of dust particles, which were released significantly before the comet's Perihelion passage – i.e. prior to reaching the closest point to the sun.
The other part, however, appears to contain more recent material: It was released when ISON passed the sun and suggests that at least part of the nucleus still existed and was active at that time.
The Max Planck researchers base their assessment on computer simulations in which they model the shape of the dust tail. "If we assume in our calculations that the comet has emitted dust at Perihelion, we can reproduce the current images quite well," says Böhnhardt.
