Abstract: This study lists the erroneous combinations in the IAUMDC Meteor Shower Database (SD) based on the version of 2018 January 13 20h35m17s. The many erroneous shower maxima may confuse observers and result in more duplicated and unjustified new entries. This paper lists the problematic maxima, the spread in the position of the radiants, the questionable velocity data and the many incorrect combinations.  The author suggests to investigate the problems identified in this analyzes in order to avoid further confusion.

 

1 Introduction

SD, the IAUMDC Meteor Shower Database (https://www.ta3.sk/IAUC22DB/MDC2007/), started from a personal working list (Jenniskens, 2006) when video observations were on the dawning.  There were not enough individual orbital data to detect minor showers and, therefore the dispersed data was collected into a meteor shower with errors in radiant position, velocity, and the activity period. This was widely accepted at that time.

SD has been filled up by many observers and researchers who worked by different standards and therefore arrived at different sources merged into one shower or in other cases some single meteor showers that got divided into several different showers.  This paper reveals the confusions in the SD by using the SonotaCo Network (http://sonotaco.jp/doc/SNM/) observations (SonotaCo, 2009).

2 The maximum of the activity

SD lists the Solar Longitude (λʘ) as the ‘ecliptic longitude of the Sun at the peak the shower activity’ but it often shows the averaged time derived from the mean descending node and not from the activity profile such as a ZHR curve.  We know that visual observations cannot determine the real time of maximum activity in many cases, for instance when the sky conditions are too bad or when the maximum occurs during daylight.  The time of the maxima, based on such data, is not representative and should not be listed.  However, old radar observations are intermittent and usually did not observe the shower maxima.  Photographic observations recorded only thousands of meteors and the node is averaged from a few meteor orbits only.  In case of video observations, the cameras installed at a small area on the Earth may not encounter the real maximum in only one or two years of observations.

DR stands for the radiant density ratio, usually of within 3 degrees to between 3 to 6 degrees and it can reduce the influence of the different sky condition. We can use the orbit data collected during ten years by the SonotaCo Network to obtain a more plausible time of maximum than what has been listed in SD.  Table 1 lists the most problematic showers for which the difference is larger than 10 degrees in λʘ (solar longitude). A more plausible maximum has been mentioned when available.  No plausible maximum has been given anymore in case of uncertain showers (see Table 5 for the comments on different Tables).  We refer to each entry by giving the three-digit shower number with the three-character code together with an additional entry number when multiple entrees for the shower exist in the SD, e.g. 004GEM1.

3 The radiant points

In the past we used to identify radiant areas with a size of 10 degrees as one single shower.  There are many such cases, even in the SD.  Table 2 lists such showers with the median values for (λ – λʘ, β). In the fourth column the value ‘d’ gives the maximum distance in degrees for the different shower entries in the SD within the shower for the combination between the shower entry listed in the 5th and 6th column under ‘Combination’.

Table 3 lists the possible related shower entries which are listed with other shower entries for which the radiant point is located within 3 degrees in (λ – λʘ, β) and the activity within 10 degrees in λʘ. The shower status is listed under the column S:

  • –2 = shower removed from the MDC lists;
  • –1 = to be removed from the MDC lists;
  • 0 = single shower;
  • 1 = single established shower;
  • 2 = to be established shower or group;
  • 4 = member of the group;
  • 6 = member of the established group;
  • 10 = pro-tempore status in the working group;
  • 40 = group member.

There may be showers present which represent activity caused by a different source and in some cases, it concerns the same shower divided into different components (see Table 5).

4  The geocentric velocity

Table 4 lists showers which have a difference in geocentric velocity vg larger than 5 km/s. For example, the difference for 195BIN is over 20 km/s!  There may be several explanations for these discrepancies, observational errors, an erroneous combination of observations, insufficient statistical significance of the data for minor meteor streams and so on.

5 Notes

Some comments in Table 5, like ‘a chance association’ or ‘indistinguishable from sporadic background’ have the same meaning that the radiant distribution and DR curves do not show any clear activity.  There are many such entries in the SD but the main concern of this paper is to show the reasons of the confusions in the SD.  We can give the details of the surveys on these problems when the occasion occurs.  The readers may feel that it is appropriate to mention this as simple errors and misprints in the SD but the author has given the lists of these problems few years ago (Koseki, 2016).

Table 3 – List of possible related entries. S is the status listed in SD, λʘ is the Solar Longitude for the time of activity, λ – λʘ, β is the Sun-centered ecliptic radiant, vg the geocentric velocity. The column ‘possible members’ mentions the IAU code of the shower / distance in degrees between the Sun-centered ecliptic radiant positions. S – shower status : –2 shower removed from the MDC lists, –1 to be removed from the MDC lists, 0 single shower, 1 single established shower, 2 to be established shower or group, 4 member of the group, 6 member of the established group, 10 pro-tempore status in the working group, 40 group member.
Here we refer to each entry by giving the four-digit shower number with the three-character code together with the two-digit additional entry number when multiple entrees for the shower exist in the SD, e.g. 0004GEM01.  This table was constructed for every entry in the original version of the SD and, therefore, it was necessary to distinguish every entry by using a different presentation from the text.

003SIA velocity difference seems to be because the influence of 005SDA; nearer and faster.
004GEM related activities: 641DRG0, 644JLL1, 914AGE0, 944TGD0, 949SGD0.
005SDA RP of SDA3 has an error.
007PER related activities: 938PEA0, 942EPE0, 981AGP0, 992GPE0, 997FTP0.
008ORI related activities: 718XGM0, 936STO0.
009DRA difficult to catch exact maximum except for its outburst.
011EVI 123NVI0 should be included in EVI / EVI1 locates over 5 degrees west of the center.
012KCG necessary to distinguish 7 years periodic component from annual activity / confused with 184GDR (peak around
λʘ = 125)/annual KCG activity does not show clear maximum.
015URS insignificant in average years and the contamination from the sporadics affects the deviation of the velocity.
016HYD Solar longitude (λʘ) of HYD3 is listed as 266.0 but its node is 256.5; the node fits the time of maximum.
017NTA many related activities: 025NOA, 215NPI, 256ORN, 629ATS, 630TAR, 631DAT, 632NET, 633PTS, 634TAT, 635ATU, 639NNT.
020COM member of COM complex; 020COM, 032DLM, 090JCO, 506FEV/DR shows a sharp peak at λʘ =261 coincident with original DLM (December Leonis Minorids) when the upper half area is used for DR calculation.
021AVB AVB0~3 are chance associations and AVB4 and 5 seem to form an independent shower with 343HVI1 and 136SLE2 possibly/not original α Virginids.
025NOA on the following ascending activities of 215NPI to 017NTA.
026NDA 026NDA2 is based on a few photographic data and differs from other entries a little / the peak of the activity is broad and the dispersion of RP is rather large / 508TPI should be included in NDA / not original Northern δ Aquariids / proper to name β Piscids (BPI).
027KSE uncertain activities / not original κ Serpentids.
028SOA a part of STA/coincident with its secondary peak λʘ = 200.
031ETA ETA5 lists parent body 1P/Halley’s node as λʘ and does not represent observational results.
032DLM core of COM complex.
033NIA NIA2, 3 and 6 seem to form a new shower / NIA1, 4 and 5 are various activities and not significant.
040ZCY possibly composite of 2 small activities; ZCY0, 1 and 3: λʘ = 16 and λʘ = 33.
043ZSE possibly chance association / ZSE0 and 1 each are based on only 1 meteor; Nos. 5688 and 3024 in Harvard Precision 413 meteors respectively (Jacchia and Whipple, 1961).
055ASC ASC1 is close to 150SOP6 / ASC0 is not significant.
061TAH 2 entries more than 10 degrees apart, both are indistinguishable from the sporadic background.
063COR 2 entries more than 20 degrees apart, both no significant identity.
069SSG not significant, though 803LSA1 is near SSG0 / SSG0 is over 5 km/s slower than the others.
076KAQ 2 entries more than 10 degrees apart, both indistinguishable from the sporadic background.
081SLY 705UYL0 should be connected with SLY0 and 2 / 424SOL0 coincides with SLY1 (possibly with SOL2) and they might represent another activity.
088ODR 3 different activities; possibly chance associations though ODR2 is slightly suggestive.
090JCO a part of COM complex’s descending skirts followed by 506FEV.
093VEL λʘ seemed to be adjusted by the supposition / RP of VEL1 is more than 15 degrees apart from the other entries.
094RGE entries are unrelated to each other; RPs are over 10 degrees in distance from each other / not significant activities.
096NCC one of unclear ANT activity / might be secondary at λʘ= 305 and third at λʘ= 275 activities.
097SCC chance groups on the descending slope of ANT activity.
101PIH PIH0 and 1 may be better displayed by 530ECV / PIH2 is quite different and 729DCO0 is possibly concerned though diffuse.
103TCE λʘ seemed to be adjusted by the supposition / the radiants of the 4 entries are about 10 degrees apart from each other / only TCE0 is a candidate for TCE; recognizable from the northern hemisphere video observations around λʘ = 315.
105OCN λʘ seemed to be adjusted by the supposition / OCN0~2 are reviews and OCN3 and 4 are intermittent radar observations; λʘ of OCN3 and 4 are more than 20 degrees different from their nodes, OCN1 and 2 coincide with 315OCA0.
106API API1 is more than 10 degrees apart from API0 and 2.
108BTU 130DME coincides with this shower.
110AAN RP of AAN0 is about 20 degrees apart from the other entries / AAN4 represents this activity.
112NDL possibly chance associations.
113SDL possibly chance association / SDL1 is over 15 degrees apart from the others.
115DCS possibly different activities; the λʘ of DCS0 and DCS2 are 325.1 and 309.1 respectively / DCS3 and 4 are about 10 degrees north from DCS0, 1 and 2.
118GNO conglomerate based on unreasonable combinations; 3 groups are more than 10 degrees apart in their positions from each other: (GNO0, GNO4, GNO5), (GNO1, GNO2), GNO3.
121NHY possibly chance association / NHY2 is close to 11EVI1 and 124SVI1, RPs of all entries are very loose.
123NVI NVI0 should be included in 011EVI / NVI1 is located more than 5 degrees west of the center.
130DME coincides with 108BTU.
133PUM very low activities/unreasonable combination: PUM0 and 1 are about 20 degrees apart at opposite position relative to PUM2 and 3.
136SLE SLE0 and 1 are of chance / SLE2 might form an independent shower with 021AVB4 and 5 and 343HVI1.
138ABO λʘ seems to be adjusted by supposition, possibly chance associations.
149NOP dispersed chance groups of ANT activity / NOP and SOP are overlapping each other / NOP1 is possible early 456MPS activity / not significant activities.
150SOP dispersed chance groups of ANT activity / NOP and SOP are overlapping each other / not significant activities; SOP6 is only slightly suggestive and 055ASC1 is close to it.
151EAU EAU2 is later than the other 2 entries and more than 10 degrees in distance from EAU1 / no significant activities.
